Prologue: This module contains both factual material and a bit of editorializing (that is, I move over from “is” theory to some “ought” theory.)  I make this statement in the spirit of "post-behavioralism,” which says one should carefully lay out your values to the audience! You are responsible for knowing the facts only.  But I hope you will analytically and critically respond to the editorial positions I take.

 

Note: I usually update chapters each year. The last complete update to this module was in the fall of 2003. Since then I have only done some minor updates, including 2005, 6, 7, 8, 9, and now 2010. I have left intact some of what I said about Iraq before the Iraq invasion. You will have to be the judge on whether I got most of it right or not.

I. Central Question

 

     How much is enough” is the single most fundamental question every nation must answer in planning its defense policy. The answer to this simple sounding question is rarely as easy as it was in the “Secret Defense Budget” game. In the real world you usually don't know exactly how much the other side can lie by or hide and you may not even be sure who the other side will be. The dramatic changes we are seeing in the world today have added even more complexity. The breakup of the Soviet Union and its empire has added new players to the game who are not bound by the rules that were once imposed on them by the Soviets. The challenge of terrorism means that we must try to defend ourselves from both low tech and high tech weapons. Thus, we are continuously reconsidering our answer to this fundamental question of how much is enough. Any answer we have will only be temporary.

 

II. U.S. Defense Policy History

 

     A brief review of U.S. defense policy history since World War II will help us understand the dilemma the U.S. faces today. Although defense policy has had many dimensions, the main focus in the last half of the 1900s was on nuclear weapons. Ironically, the nuclear bomb was the weapon that made us a superpower and it was also the weapon that most threatened us. Today nuclear weapons continue to be a great concern for two reasons. The crumbling of the world's second superpower has created the possibility of the loss of control over many weapons and the expertise to build such weapons. So let us consider the question of “how much is enough” thinking first about nuclear weapons.

 

     Immediately following World War II the answer to the question of how much is enough was fairly easy. As long as the U.S. was the only nation that had nuclear weapons, it could deter any immediate attacks with the threat of massive retaliation.

 

     However, the massive retaliation answer proved sufficient for only a few years. The Soviet Union quickly developed its own weapons. In the early 1950s the U.S. also found in Korea that merely having nuclear weapons did not deter other nations from attacking U.S. allies with conventional forces. Nevertheless, Eisenhower's threat of using nuclear weapons did ultimately bring that regional conflict to a halt. But nuclear weapons did not give the U.S. a clear victory. The U.S. needed a new answer that was not entirely nuclear.

 

     Based upon the Korean experience and later what the U.S. saw as aggression in Vietnam, a new answer began to evolve‑‑flexible response. The U.S. still relied primarily upon its ability to inflict massive nuclear destruction on those who would attack the nation directly. Americans were frightened when they saw the Soviets developing rocket capabilities. America began pouring massive amounts of money into science, engineering, and into a space program in the late 1950s. About the same time the U.S. also began to develop new kinds of units designed to fight guerrilla forces wars using what were called "counter‑insurgency" tactics. This was the premise of the Green Berets. They and the American “can-do” attitude were supposed to enable us to win in places like Vietnam.

 

     A great shift in nuclear strategy took place following the 1962 Cuban Missile Crisis. The Soviets, feeling that their own nuclear capabilities left them far short of what was enough, tried to quickly catch up by placing warheads ninety miles off the Florida coast. As all who lived through that tense time remember, Kennedy and Khrushchev played a game of nuclear chicken in which roughly 4,000 U.S. warheads caused the Soviets, with their few hundred, to blink.  (By the way, you can see an excellent “docu-drama” about that crisis in the 2001 movie “Thirteen Days.”)

 

     The result was a "never again" vow on the part of the Soviets. They embarked on a catch‑up race. They went on a massive building program. The U.S. responded. Both sides built more and more missiles. Both worried about whether they had enough. It was like playing the Secret Defense Budget game without knowing how much you needed to spend to be safe from attack. So you spent and built as much as you could. Each side was concerned about the other side having what was called "first strike capability." This refers to the ability to destroy the other side's weapons by shooting first thereby rendering them incapable of striking back. Attempting to achieve invulnerability through such measures as increasing the mobility of weapons or hiding them in protected holes in the ground – concrete hardened silos -- became more important. This improved second strike capability, the ability to withstand a first strike and then strike them back and inflict unacceptable damage on them. But these measures also made each side less sure about what the other actually had. So the whole process of trying to achieve security created additional incentives to build more weapons.

 

     New technology like MIRV's (multiple‑targeted independent reentry vehicles), SLBM's (submarine launched ballistic missiles), and more accurate missiles and more easily concealed missiles (like the cruise missiles) increased uncertainty even more. Even defensive systems, like SDI (the Strategic Defense Initiative, popularly known as "star wars"), increased the speed of the race. Any attempt at defense would be seen by the other side as a possible way to gain the ability to strike first and be able to withstand the response. “How much was enough” kept increasing.

 

     By the mid 1960s the guiding philosophy of massive retaliation made no sense whatsoever. The new strategy created by both sides having large nuclear arsenals was known as MAD‑‑mutually assured destruction. “MAD” was an appropriate acronym because the arms race seemed "mad" in many respects. By the late 1980s both sides had roughly 14,000 warheads, enough to destroy the world as we knew it many times over. With more weapons, the problems of command and control increased and the risk of accident grew. Neither side seemed able to escape. Testing these weapons that were supposed to protect us threatened us – the snow that fell from the sky and the milk we drank in the 1960’s began to have traces of radiation. (The psychology of this situation is perhaps best captured in the 1960’s movie “Dr. Strangelove,” a movie that all educated people should see at least once in their lives.) The best that could be done was slow the race down a bit in a series of arms agreements. We began to do this with a ban on atmospheric testing and later a ban on anti-ballistic missile systems (the ABM Treaty, which the Bush administration wishes to abandon in order to build the SDI system).

 

     The race placed a heavy burden on the economies of both sides. The economic burden proved unbearable for the Soviet economy. That, along with a new generation of leaders and followers who took incredible personal risks to bring about change within the USSR and Warsaw Pact nations, brought about the breakup of the USSR and its allies. The answer to the question of “how much is enough” began changing dramatically.

 

     With a fast fading "evil empire" (President Reagan’s term for the USSR), serious reductions in nuclear arms began taking place. Shortly, the U.S. and the component nations of what used to be the USSR will be down to well under half of what they had at their peak. But agreements are not always easy. Although the Russians signed the Strategic Arms Reductions Treaty II (START II) that promised to reduce arms to no more than 3,000 to 3,500 warheads, the Russian Duma (legislature) has refused to ratify it. Nationalists and still defiant communist members feel that it put them at a disadvantage. The US has its own problems in finalizing agreements as well. The Republican majority in the Senate in the fall of 1999 refused to ratify the comprehensive nuclear test ban, even though the President Clinton had signed it.  It had been signed by over 150 other nations, but thus far only a little over 50 have ratified it. Just like you in the Money Game simulation at the beginning of the semester, senators did not feel they could trust other nations enough to say we would forego underground nuclear testing ourselves, even with sophisticated monitoring equipment.  Nevertheless, leaders continue to negotiate. In the summer of 1999 the US and Russia agreed to begin a new round of talks (START III) that will further reduce warheads to between 2,000 and 2,500, even though the last reductions have not yet been met (Barry Schweid, "US, Russia to Seek," The State, July 28, 1999, A4). Little more than talks took place until 2003 when the U.S. and Russia signed the Strategic Offensive Reduction Treaty (SORT) that calls for about the same limits, in the range of 2,000 weapons. That treaty set little more than a goal, with little on tactical weapons or the destruction of existing strategic warheads.

 

As of this writing (fall 2010), the Obama administration has made significant progress in arms control with Russia, having signed a new treaty in April of 2010. It would further reduce the current numbers of nuclear weapons from about the 4,000 each side currently has to about 1,500 each. But Republican opposition has prevented ratification in the Senate as of this writing. However, both sides have agreed to continue to abide by the existing treaty until the new agreement is ratified. So the talks continue, but more with Republicans than with the Russians! Some agreement will probably be eventually reached because it is in the interest of both sides to reduce arms and spending. Neither can afford to waste money on nuclear weapons in light of new defense needs in combating terrorism and in light of economic needs.

 

            The horrific attacks on the World Trade Towers and the Pentagon and perhaps other places have led to further change in US Defense policy. The Bush administration called the new policy the “Bush Doctrine.” It asserted that the US would make preemptive military strikes anywhere in the world where it saw the danger of a terrorist attack, with or without the approval of allies or the United Nations. In a sense this took our foreign policy a full circle to the years preceding WWII when our policy was to take unilateral action and avoid alliances.

 

            While this policy certainly had emotional appeal and seemed highly justified in clear cases where plans are made like the ones carried out in September 2001, it was not without risk – great risk. Once we set the precedent that we may attack any nation that posed a threat, did not that give license to others to do the same? South Korea and North Korea? China and Taiwan? Israel and any of the Arab nations that have threatened her existence? India attacking Pakistan because they know that Pakistan, unlike Iraq, already has nuclear weapons and the ability to deliver them and has clearly threatened their use? Where would it all stop once the precedent is set?

 

            Setting off conflagrations around the globe among nations that have nuclear weapons is not the only danger, even if it is the most dramatic danger. Machiavelli warned that “the ambition of men is such that, to gratify a present desire, they think not of the evils which will in a short time result from it.” It is our ambition to find security, and we have developed great pride in our military might (pride or “hubris” is another danger). We might overextend ourselves across the globe into nations that we feel pose a potential danger to ourselves. The evil that will come is that we will create enemies where we at least had shaky alliances before. We might spend our wealth in trying to maintain security across the globe, not this time in the name of containing communism, but in the name of containing and destroying terrorism. It has happened before to other great empires. It happened to us in Vietnam, and even the success of the Gulf War in the early 1990s should not erase that memory. We should have learned from all of our history that we are better off not going it alone. We had many allies in WWII, relatively fewer in Korea, a world alliance in the Gulf War, European support in Bosnia and Kosovo, and world support in our war to topple the Taliban in Afghanistan. Indeed, one could argue that we had no choice in that war because we were attacked and the Afgans openly gave safe harbor to those who attacked us. But how long do we stay there after we go in? How long do allies stay with us when we have alienated them by going it alone in another way they were opposed to? And that gets us to Iraq.

 

(Note: I wrote the next paragraph just before the Iraq War began. The initial shooting phase was over fairly quickly and cheaply in both lives and money – but the low level conflict that has followed has cost us over 4,400 military lives (as of October 2010), well over 30,000 wounded, and thousands more civilian lives (counting the lives of our allies in Iraq), and about over a trillion dollars as of 2009. Some estimates that count long-term costs, including cost to help wounded with life-long disabilities, and indirect costs are in the range of $3 trillion.)

 

Iraq is different. Containment has largely worked. Saddam is certainly evil and homicidal, but he, unlike the crazies who flew those planes, is not suicidal. Threat of retaliation does keep him in check. He is most likely to strike when he is cornered and feels he will die regardless of what he does. So we do have a choice. And that choice should take into account what we will do after the war, even if it is a relatively cheap and easy win. The cost of peace may be far higher after the shooting is over. What will long-term American occupation say to all the people of the region who already hate our influence and culture? How many more enemies will it create? Are we prepared to pay the cost of “the evils that will in a short time result?”

 

President Obama changed the unilateralist Bush doctrine shortly after he came into office in 2009. He pledged the U.S. to work with allies and in concert with international organizations—a multilateral approach. That in effect takes us back to the position that the first President Bush laid out after the end of the Cold War around 1990. 

 

 

III. Contemporary Needs and Concerns

 

     So how much is enough today, at least in so far as nuclear weapons and deterrence are concerned? Back during the 1960s, then Secretary of Defense Robert McNamara calculated that the U.S. needed 400 warheads to inflict unacceptable damage on the Soviets. Fear of first strike capacity complicated that calculation. Other experts have calculated that somewhere in the range of 500 warheads would be sufficient to deter any rational opponent today. No one except the Russians could even come close to knocking out that force with a first strike.

 

     While all of this is hopeful, three major areas cause worry: nuclear proliferation, nuclear terrorism, and stability of governments that have nuclear weapons, including Russia.

 

     Nuclear proliferation may be the single greatest remaining concern. During the Cold War more and more nations felt they needed nuclear weapons of their own either to gain an advantage over their enemies or to prevent being intimidated. The so‑called "nuclear club" now includes about nine nations with a handful of others that could develop them (see the table in chapter 5). Most notably, Iran seems intent on developing its capability. A continued danger exists of proliferation as third world nations seek weapons from former Soviet republics that are in desperate economic straits. Moreover, one of our allegedly best allies, Pakistan, has been willing to sell nuclear technology. Proliferation makes control and agreements more difficult, and it increases uncertainty and adds to the likelihood of accidents.

 

     Proliferation of weapons to terrorist groups is a closely related grave concern, perhaps the most grave concern after September 11, 2001. News reports in recent years indicate that weapons grade materials are being smuggled out of former Soviet republics. Some of these materials, or worse yet, intact weapons, could find their way to terrorist groups who might be tempted to engage in nuclear blackmail. They do not need missiles to deliver these weapons. All they need is a container on one of the thousands of container ships that go into ports across the U.S. Even if it is a crude weapon, the destruction from a small nuclear blast in Boston or New York or Baltimore or San Francisco or Charleston or Savannah or Jacksonville or any number of other ports would make the twin towers atrocity look small.

 

     Nations like Pakistan, which have nuclear capabilities and have in fact tested nuclear weapons, are of particular concern. Islamic Pakistan has had a long-term conflict with primarily Hindu India ever since the Pakistan was created when India was partitioned following its independence from Great Britain in 1947. The government of Pakistan has been much less stable than that of India. It has to deal with many of its own Islamic extremists who would impose a religious state if they gained power. This gives the U.S. two reasons to help foster a stable government in Pakistan. First, cooperation is needed in dealing with the extremists that move in and out of Afghanistan from the mountains in Pakistan, which has a long common border with Afghanistan. Second, the nuclear capability of Pakistan makes it important in its own right. 

 

     The U.S. must also worry about our relationship with Russia. Economic distress led to a transformation of a fragile democratic republic into an authoritarian state led by former head of the KGB, Vladimir Putin. Using oil revenues to fund economic prosperity, Russia is starting to send signals that it might start attempting to rebuild its empire. Russia has reacted quite negatively to our efforts to extend membership into our NATO alliance to some former Soviet satellite nations. As tension grows, agreements to limit the building of nuclear weapons might begin to crumble. A few years ago, one extreme nationalist politician, Vladimir Zhirnovsky, advocated rebuilding the Soviet empire by force. If the Balkan nations resisted, he wanted to use large fans to blow nuclear radiation over them. In short, it is in our national interest to stabilize the Russian economy and give them a stake in maintaining the peace.

 

     A new emerging area of concern is not our security on land, air, sea, or even outer-space. Rather it is a new kind of space, cyber space. Consider how much damage could be done to our economy if economic records and transactions were compromised or destroyed. Commerce and business would come to a standstill. The US is just starting to gear up with "cyber-security" for business and state a local governments, as well as of course for the military, whose computer systems have been under attack for some time now. Protecting computer systems and information is critical to the well being of any nation today. Recently outsiders were able to hack into our military drone program and see what the controllers of these drones were seeing as these drones flew over potential targets. 

 

     Considering these new realities, in building our defense, how much is enough today? The answer must go well beyond nuclear weapons, but let us consider the nuclear part of the answer first. Total nuclear disarmament is still out of the question from the point of view of most who study these questions. The U.S. probably needs to maintain somewhere in the range of 500 warheads that can be delivered to any nation in the world that would create a threat with their own nuclear weapons. We will not be entirely free of MAD for some time to come.

 

     Movement to that level of roughly 500 must take place gradually. The U.S. must see how the republics of the former USSR, most especially Russia, reduce their weapons and build stable economies and governments.

 

     The U.S. must do all that it can afford to do to help this process along. Former President Nixon faulted the first President Bush for not doing more to help stabilize the Soviet economy. The U.S. must do all it can to encourage wealthy allies to help the new republics. Helping is certainly in their interest. America's economy cannot afford to foot the bill if another arms race takes place. Indeed, the U.S. could not have even afforded the Gulf War had it not been for the financial help from Saudi Arabia and Japan. The Iraq and Afghan wars have been a major drain on our economy since 2001.

 

     During the 2000 presidential campaign, candidate Bush vowed that under his administration the U.S. military would not become involved in “nation building.” It was a popular rhetorical line in a nation that still harbored isolationist tendencies. Most Americans feel that we spend far too much money on foreign aid. Typically most incoming American government students think that we spend more on foreign aid than on Social Security. They are wrong by a factor of more than ten! Yet Bush did not withdraw troops from duties in Kosovo and engaged in nation-building in Afghanistan following the fall of the Taliban, even though that is not the term that the White House used (“a rose by any other name …”). Afghanistan  was put on the back-burner and mostly ignored after we invaded Iraq in 2003. By the time President Obama had come into office, the situation in Afghanistan was dire. President Obama renewed the commitment, at least for a limited time, after a painful review of options. He sent in a surge of troops pushing the number up over 100,000. Will that be enough? How long will they have to stay?  We do not really know. As of this writing in 2010, things are again not going as well as hoped. No outside power in history has been able to transform or hold Afghanistan—including the Russians, the British or even all the way back to Alexander the Great. Are we guilty of hubris to think that we can?  

 

     After the fall of Saddam's government in Iraq, which we essentially did alone, we had another long-term commitment in nation-building. While we have been able to withdraw our combat troops, we still have tens of thousands of non-combat personnel there. Moreover, the ability of the political leaders in Iraq to work out their differences and form a stable government and minimize acts of terrorism by the various competing groups is far from certain. Our success may be measured in an ironic way: when the government feels strong enough to ask us or demand that we leave. 

 

     The U.S. must do all that it can to control and limit nuclear proliferation. This includes agreements, cooperation among police and intelligence agencies, and helping defuse conflicts that lead other nations to feel they need weapons. The U.S. has no choice but to play a leading diplomatic role in the world. We are in effect blackmailed into this role by the existence of weapons technology we helped create. And the world certainly looks to the U.S. for leadership. While the infamous videotaped Clinton testimony before Special Prosecutor Ken Starr’s grand jury was being shown on tv in early 1999, the President was receiving an unusual and warm standing ovation at the U.N. from leaders from all over the world. The message was not that the world community approved of his personal immoral behavior, but that he had their support in leading the strongest nation in the world to play a leading role in world affairs and that they considered these world affairs to be much more important.  That is why the Senate's refusal to ratify Clinton’s test ban treaty was so important in late 1999. President Bush had no new initiatives here. But after President Obama negotiated and signed a new treaty aimed at further reducing nuclear weapons, the Senate has as of this writing refused to ratify it.

 

     Ironically, this new situation created a better justification for a limited Strategic Defense Initiative system (sometimes called “Star Wars”) than ever before. While it only destabilized things in a nuclear arms race with another superpower, it made some sense if it could deflect a few weapons of a small power, whether they be launched by intent or by accident. Unfortunately, a fully operational SDI system would be of little use against low altitude Cruise type missile delivered weapons or against terrorists who would likely smuggle a weapon to its target, for example, aboard a tramp steamer. However, given the high cost of such a limited system and its doubtful usefulness along with the severe pressures that exist on the federal budget, SDI remains an idea whose time may not yet have come. Despite this, the George W. Bush administration pressed ahead with efforts to build the system in 2001. Whether the post 11 September reality of vulnerability to low tech weapons will change this plan is too early to tell at this writing. However, though the Bush administration continued to pursue building a limited SDI system, the Obama administration may choose another direction.

 

     While the U.S. probably no longer needs or can afford huge military outposts to contain another superpower, the nation does need a modern conventional army that can protect vital interests elsewhere. While the causes of Iraq's invasion of Kuwait in 1990 can be debated, most would agree that the U.S. needs the capacity to stop such actions with forces that can be rapidly deployed if necessary. It is these forces that are most useful in going after small groups of terrorists hiding in third world nations. Rapid deployment forces could also be used to help quickly with natural disasters here and abroad. But to be successful in the long run, we need the help of other nations in these actions. We do not have unlimited wealth. I would argue that probably the most important way to combat terrorism in the Middle East has nothing to do with the military-- it has to do with rebuilding our energy sector so that oil is not our greatest source of energy. Even if you do not believe in global climate change, you should consider that some of the money you pay for every gallon of gas goes to fund the activities of people who hate us. And some of that goes to buy weapons that kill our sons and daughters who are fighting these radical people.

 

IV.  When To Use Force

 

     When to use these conventional forces is the other great vexing question for U.S. foreign policy. Since the Vietnam fiasco, the U.S. has deployed conventional forces in a number of places, some quite successfully and some disastrously. (As I noted a number of years ago, it seems that every time I edit this chapter I must add another military intervention to the list—it is now a very long list that only goes back about three decades!)

 

  • President Carter attempted to deploy a small number of troops in a rescue mission of the U.S. hostages held in Iran in 1980. The mission ended at their rendezvous point in the desert where a helicopter crashed into the transport costing American lives and possibly costing Carter the next election to Ronald Reagan.
  • President Reagan sent marines to help keep the peace in Lebanon and before they knew it they were in the middle of a shooting war. We left after 241 were killed by a truck bomb that collapsed the hotel in which they were sleeping. Reagan was lucky that he had some time to recover politically before the next election.
  • Later he sent troops in a successful mission to overturn the pro-Cuban communist government in Grenada.
  • President Bush sent troops into Panama to "arrest" President Noriega for his activities in drug smuggling. The real interest of the U.S. here was the security of the Panama Canal, a vital commercial link between the two major oceans that border the east and west coasts of the U.S.
  • Of course, Bush also sent troops to the Middle East in Operation Desert Shield and Desert Storm – the Gulf War. These operations against Iraq were quite successful in driving Iraq from Kuwait, where access to oil (in both Kuwait and Saudi Arabia) was the vital interest. However, Bush stopped the war before Saddam Hussein was toppled. He endangered both those within his nation (the Kurds--whom he killed at almost any opportunity) and those without. American troops remained in the area enforcing a “no-fly zone” until the 2003 invasion.
  • Bush's going-away present to President-elect Bill Clinton in 1992 was a troop commitment in Somalia—an action we took all by ourselves. The mission was humanitarian--end starvation that was the result of clan warfare taking place all over the nation. We did succeed in at least temporarily ending the starvation, but we were unwilling to pay the cost of disarming the clans completely. The clan leaders hid their weapons and waited while giving minimal cooperation. As a few American troops died, the nation lost patience and pulled out. Once again, the clans are back in control. The area has been sliding back into chaos and is now the center of pirate activity off the coast.
  • In September of 1994 President Clinton made his own troop commitment, this time much closer to home. American troops went into Haiti after we negotiated (with a great deal of help from former President Carter) the withdrawal of the military general who were ruling the island nation. Once in place, the Americans--unlike in Somalia--disarmed the Haitian military and police. The democratically elected President Aristede, who was driven from the country after his election by the generals, regained his office. The nation is now struggling to meet the revolution of rising expectations (remember this idea?). Most American troops were withdrawn. By the end of the year 2000, only a few dozen troops were in Haiti.
  • In late summer of 1998, President Clinton sent unmanned weapons (Cruise missiles) to bomb alleged terrorist camps and chemical weapons facilities in Afghanistan and Sudan that were thought to be associated with terrorist Osama bin Laden. This was in retaliation for the bombing of embassies in Africa.
  • In 1999 the US and NATO allies intervened in Kosovo in the name of humanitarianism as Yugoslavian led Serbs tried to “ethnically cleanse” that region of their nation of ethnic Albanians, who comprised 80% of the population. After nearly 80 days of bombing, the Serbs agreed to withdraw. Eventually the new Yugoslavian government turned over former President Milosovic to the U.N. to be tried for war crimes.
  • Then came Afghanistan. In Afghanistan, the U.S. has been pursuing terrorists led by Osama bin Laden since the 11 September attacks. Having driven bin Laden underground and scattered his forces and the supporting Taliban forces, which have been fighting an escalating guerilla war in recent years against us and our NATO allies and the new government that has little control outside the cities, where only about 20% of the population lives.
  • In Iraq were we overthrew Saddam Hussein in 2003 and have been trying to foster a stable government that is not endangered by a civil war between the religious and ethnic groups there (Shia, Sunni, and Kurd, to name the largest three.)
  • President Obama sent about 30,000 additional troops to Afghanistan in 2009-10 to try and reverse the tide, boosting the numbers to over 100,000. The reduction in Iraq made Afghanistan our largest commitment in combat. By the last few months of the year of 2010, we were suffering about 1-2 KIA a day with a total over 1,000 for that effort, most of which took place in 2009-2010.

 

     A. Theoretical Guidelines

 

     With this short history in mind, what rules should we use in deciding where to send American troops to risk their lives? President Reagan's Secretary of Defense, Casper Weinberger, laid out several principles that might be used as guidelines in making this kind of decision. 1) A vital national interest must be at stake. 2) The President must have public and congressional support. 3) The mission must have objectives that are achievable through military means (presumably, defeating and disarming are ok but complex social overhauls and "nation-building" are not military capabilities). 4) When you do go in, go in with overwhelming force--avoid gradual escalations that create sunk costs which then justify further commitments. 5) You must have a clear exit strategy, that is, a clear observable point at which you say you have achieved your goal and can leave without loss of lives or face.

 

     Other experts have added a few other guidelines we might consider. Have a clear chain of command so that those on the ground know who is calling the shots and so that mid-level commanders do not go too far or hold back when they should not. Never underestimate your opponent. They may not look like an army, but weapons can kill you even when fired by people not wearing uniforms. Others advise us to avoid getting involved in civil wars where one cannot help taking sides and then becoming the target of the other side. This was the danger in sending peace keeping troops into Bosnia, where we have been seen by the Serbs as taking the side of the Bosnians. And it is the great danger in Iraq, where at least three major ethnic groups have long battled for supremacy. In Afghanistan, the religiously fanatic Taliban arose following years of civil war after the Soviet withdrawal in the late 1980s. Afgans supported the Taliban because it seemed able to bring about peace, if not prosperity, to the nation. Afghanistan is more a collection of warring tribes and clans than a nation with a single identity.

 

     B. In Practice

 

     While these ideas sound reasonable in theory, they are difficult to use in practice because they are subject to interpretation as they are applied to concrete situations. For example, deciding what is in our vital interest is not an easy matter except in obvious situations. Haitian refugees flooding ashore in Florida is certainly a national interest--we must keep our borders secure and enforce orderly immigration. But is this a VITAL interest? Can humanitarian concerns be part of the national interest? Is preserving order in the world a national interest for a nation that has the world as its market? Is preserving our role as a leader in NATO a vital national interest? (This is one justification Clinton used for proposals to send peace-keeping troops to Bosnia.)

 

     While public and Congressional support is certainly desirable, what if time is too short to obtain this support? The War Powers Act of 1973 recognized the President's power to act in an emergency, though it requires congressional consultation if time permits and requires congressional approval if the troops stay very long.

 

     The criterion of being achievable through military means is not at all clear because the military has many capabilities, including running the civil affairs of a nation, as it has in many instances. How is this different from the initial stages of nation building?

 

     Exit strategies (that means how to get out) may seem clear when you go in. But they may not work out when allies renege on commitments (like they did in 1998 in forcing Saddam Hussein to allow inspections) or when things do not go as planned.

 

     Finally almost all areas in which we have involved ourselves entail some kind of civil strife or conflict. So this can't always be used as an excuse to stay out.

 

     The bottom line is that we will have to proceed on a case-by-case basis. The answer will rarely be clear. (Remember no perfect answers?) Presidents will decide and we will praise them when things work out well (Grenada, Panama, and the Gulf War) and second-guess them when things go badly (Vietnam, Lebanon, Somalia). On which side of the list will Iraq and Afghanistan be? Voters will ultimately hold presidents accountable if the disaster was too big and too recent.

 

     However, this does not mean that we should not debate and discuss. That is a part of being an open democratic republic. The guidelines may not always provide precise answers, but they at least force us to consider many of the important questions and to consider how an intervention will be the same or different than previous ones. Systematic analytical thinking--even if difficult--is a better way to develop foreign policy than proceeding on emotion and instinct. 

 

     The last element in the answer to “how much is enough” was well captured in Ross Perot's quip: we can't be a military superpower unless we are an economic superpower. Indeed, the less the nation spends on defense, the better. That money is better spent on education and basic research and the infrastructure. Energy independence is another part of the equation. The less the U.S. is dependent on foreign energy supplies, the less likely the nation is to have to stop a dictator who tries to engage in energy blackmail.

 

V. Looking to the Future

 

     Rapid changes in the world have created exciting new possibilities and have posed new challenges for the United States. Clearly, the question of "how much is enough" today includes dramatically fewer nuclear weapons along with dramatically more emphasis on international negotiation, cooperation in helping stabilize other nations of the world,  security measures against terrorism, including cyber terrorism, and vigilance as the situation evolves.

 

     Events in recent years seem to indicate some positive trends and some negative trends. Russia found help in financing its space program from Germany, which is sending up their own astronauts in Russian space craft. But their economy is so bad that NASA sought money to pay Russian workers to build their part of the space station program. Yeltsin's October 1994 visit to the U.S. was centered around requests for more trade, not aid--a welcome request from the U.S. point of view. But the economic reforms were done badly--too much state owned industry were given to former communist leaders who did not know how to run it. Why? Yeltsin was buying their political support. By 1998 the Russians needed massive loans to hold up their currency. Having opposed the mass killing of civilians in Bosnia and then Kosovo, the allies did little as Russians bombed civilians in breakaway provinces within their own borders. The new leader of Russia, President Putin, the former head of the KGB, took hard line approaches to internal Russian security. But he is cooperating with NATO and the UN in fighting terrorism and gave the U.S. military permission to use Russian land as bases of operation against terrorists in Afghanistan.  The NAFTA (North American Free Trade Agreement) treaty gives the U.S. more leverage over Mexico on environmental matters and probably will reduce the influx of illegal immigrants into the U.S. And the GATT (General Agreement of Trade and Tariffs) was approved by the U.S. Congress after some delay. This will increase trading relationships among nations, making military conflicts less likely. The WTO (World Trade Organizaiton), which followed GATT, has attempted to further open the world economy, but it has met stiff resistance from a wide range of protestors wherever it meets. NATO finally forced the Serbs to come to the peace table and Milosevic is on trial for war crimes. Progress has been made in the Balkans. People are much more free to travel now that they have one set of license plates so that your ethnicity is not advertised on your car. But resettlement back into home areas by people driven out through ethnic cleansing has not gone well. And ethnic outbreaks continue to take place. The PLO along with the more militant Hamas and the Israelis seemed to be locked in an endless dance of death and destruction. Israel reacts harshly to each terrorist attack and seems to have been successful only in creating more would-be suicide bombers. The Israelis continue to build settlements in land that the Palestinians consider to be theirs. We cannot broker and lead any further agreements while we are engaged in wars in nearby lands, even though after the terrorism of 11 September, the U.S. has even more incentive to try and broker a peace to remove one ongoing source of conflict that fuels extremism. Iraq seems more stable and independent in 2010 than it did in 2008--they finally seem to be forming a government based on some compromise, an idea with which they seem not very familiar. At least the conflict in northern Ireland seems to have subsided at the moment. We have reached an agreement with North Korea on North Korean nuclear reactors that could have created materials for additional nuclear weapons beyond the few crude ones they have tested (though this deal has been an on and off again thing over several years). Finally, although the attacks of 9-11 indicate that we are far from secure, the response from nations around the world in the Afghanistan phase of our response was encouraging to those who value “ordini” and encouraging in the sense that we had the support of the world. But our extension of this war to Iraq undercut much, if not most of that support. That weakened the support we once had in Afghanistan, so every year we are more alone in that effort. All these things are connected!

 

     Machiavelli warned us that “ordini” rarely lasts for long. Whatever agreements and coalitions that we are able to build out of the blood and suffering will be at best short term. But that is the nature of politics. Each generation must do its best to step forward again after the inevitable setbacks – yes, that is a normative statement.

 

     Two final comments. Given the interdependency of all national economies, one cannot make as clean a distinction between domestic and foreign policy as one could in the relatively more simple days of super-power competition. At least then we knew who the enemy was. Judging from the litany of events in the preceding paragraphs, we seem to have a new enemy every few months, and each presents new challenges. We will continue to struggle over the question of how much is enough.

 

    Finally, it may be that military power—what political scientists often call hard power— is less important than economic power—what political scientists call soft power. Maybe blue jeans and Coca Cola and computers and rock and roll and jazz and basketball and even football are more powerful in transforming nations than all our military might. The fanatics may be able to fight low level wars of insurgency for decades against our military—in these situations time is on their side. Americans usually are not willing to send their sons and daughters into conflicts when no clear end is in sight. But time is on our side when they are fighting against western culture and all its many attractions. They can slow down the invasion of rock and roll, but young people will eventually seek it out and embrace it and the individualistic consumer values that go along with it will eventually win out—not at a cost to us, but at a profit!
