Lessons for an Exit Strategy

There have been conflicting reports about the timing of American troop withdrawals from Iraq. Gen. George Casey, commander of U.S. forces there, has announced that the United States intends to begin a "fairly substantial" withdrawal of U.S. forces after the projected December elections establish a constitutional government. Other sources have indicated that this will involve 30,000 troops, or some 22 percent of U.S. forces in Iraq. Some high-level statements from Baghdad have indicated that the beginning of withdrawals may be delayed until next summer. On either schedule, progress is dependent upon improvements in the security situation and in the training of Iraqi forces.

A review of withdrawal strategy therefore seems in order. For one thing, how are the terms "progress" and "improvement" to be defined? In a war without front lines, does a lull indicate success or a strategic decision by the adversary? Is a decline in enemy attacks due to attrition or to a deliberate enemy strategy of conserving forces to encourage American withdrawal? Or are we in a phase similar to the aftermath of the Tet Offensive in Vietnam in 1968, which at the time was widely perceived as an American setback but is now understood as a major defeat for Hanoi?

For someone like me, who observed firsthand the anguish of the original involvement in Vietnam during the Kennedy and Johnson administrations, and who later participated in the decisions to withdraw during the Nixon administration, Casey's announcement revived poignant memories. For a decision to withdraw substantial U.S. forces while the war continues is a potentially fateful event. It affects the calculations of insurgents and government forces alike, so that the definition of progress becomes nearly as much a psychological as a military judgment. Every soldier withdrawn represents a larger percentage of the remaining total. The capacity for offensive action of the remaining forces shrinks. Once the process is started, it runs the risk of operating by momentum rather than by strategic analysis, and that process is increasingly difficult to reverse.

Despite such handicaps, the decision to replace U.S. forces with local armies during the Vietnam War -- labeled "Vietnamization" -- was, from the security viewpoint, successful on the whole. Between 1969 and the end of 1972, more than 500,000 U.S. troops were withdrawn. American involvement in ground combat ended in early 1971. U.S. casualties were reduced from an average of 400 a week in 1968 and early 1969 to an average of 20 a week in 1972.

These measures were possible because, after the failure of Hanoi's Tet Offensive, the guerrilla threat was substantially eliminated. Saigon and all other urban centers were far safer than major cities in Iraq are today. Saigon controlled perhaps 80 percent of the country with relatively well-established front lines. Vietnamese army units were increasingly able to repel offensives from the regular forces of Hanoi.

When the Vietnamese army, with substantial U.S. air support, broke the back of the North Vietnamese all-out offensive in 1972, Vietnamization could be judged a success. Shortly afterward the North Vietnamese accepted terms that they had rejected for four years. (That they did, however, does not settle the debate over whether a different withdrawal rate -- slower, faster or none at all until after a settlement -- could have speeded that day.) Three years later, these results were reversed, not because of internal violence but because of an external attack by Hanoi's conventional military force, in violation of every provision of the Paris agreement.

America's emotional exhaustion with the war and the domestic travail of Watergate had reduced economic and military aid to Vietnam by two-thirds, and Congress prohibited military support, even via airpower, to the besieged ally. None of the countries that had served as guarantors of the agreement was prepared to lift a diplomatic finger.

All this demonstrated two principles applicable to Iraq: Military success is difficult to sustain unless buttressed by domestic support. And an international framework within which the new Iraq can find its place needs to be fostered.

History, of course, never repeats itself precisely. Vietnam was a battle of the Cold War; Iraq is an episode in the struggle against radical Islam. The stake in the Cold War was perceived to be the political survival of independent nation-states allied with the United States around the Soviet periphery. The war in Iraq is less about geopolitics than about the clash of ideologies, cultures and religious beliefs. Because of the long reach of the Islamist challenge, the outcome in Iraq will have an even deeper significance than that in Vietnam. If a Taliban-type government or a fundamentalist radical state were to emerge in Baghdad or any part of Iraq, shock waves would ripple through the Islamic world. Radical forces in Islamic countries or Islamic minorities in non-Islamic states would be emboldened in their attacks on existing governments. The safety and internal stability of all societies within reach of militant Islam would be imperiled.

This is why many opponents of the decision to start the war agree with the proposition that a catastrophic outcome would have grave global consequences -- a fundamental difference from the Vietnam debate. On the other hand, the military challenge in Iraq is more elusive. Local Iraqi forces are being trained for a form of combat entirely different from the traditional land battles of the last phase of the Vietnam War. There are no front lines; the battlefield is everywhere. We face a shadowy enemy pursuing four principal objectives: (1) to expel foreigners from Iraq; (2) to penalize Iraqis cooperating with the occupation; (3) to create a chaos out of which a government of their Islamist persuasion will emerge as a model for other Islamic states; and (4) to turn Iraq into a training base for the next round of fighting, probably in moderate Arab states such as Egypt, Saudi Arabia and Jordan.

North Vietnamese forces possessed heavy weapons, had sanctuaries in adjoining countries and numbered at least a half-million trained troops. Iraqi insurgents number in the tens of thousands and are lightly armed. Their most effective weapon is a homemade explosive, their most effective delivery system the suicide bomber and their most frequent targets unarmed civilians.

The Iraqi population has shown extraordinary equanimity in the face of this deliberate and systematic slaughter. In the end, its perception will determine the outcome as much as the military situation does. It will know how secure it is; it will determine the sacrifices it is prepared to make.
