You may not have seen this article a little more than a year ago in The Atlantic Monthly but it's something you need to read. At the invitation of the magazine a group of some of the sharpest strategic thinkers and defense analysts in the United States came together to "war game" a potential strike against Iran. The essence of their conclusions:
The most important hidden problem, exposed in the war-game discussions, was that a full assault would require such drawn-out preparations that the Iranian government would know months in advance what was coming. Its leaders would have every incentive to strike pre-emptively in their own defense. Unlike Saddam Hussein's Iraq, a threatened Iran would have many ways to harm America and its interests. Apart from cross-border disruptions in Iraq, it might form an outright alliance with al-Qaeda to support major new attacks within the United States. It could work with other oil producers to punish America economically. It could, as Hammes warned, apply the logic of "asymmetric," or "fourth-generation," warfare, in which a superficially weak adversary avoids a direct challenge to U.S. military power and instead strikes the most vulnerable points in American civilian society, as al-Qaeda did on 9/11. If it thought that the U.S. goal was to install a wholly new regime rather than to change the current regime's behavior, it would have no incentive for restraint.
What about a pre-emptive strike of our own, like the Osirak raid? The problem is that Iran's nuclear program is now much more advanced than Iraq's was at the time of the raid. Already the U.S. government has no way of knowing exactly how many sites Iran has, or how many it would be able to destroy, or how much time it would buy in doing so. Worse, it would have no way of predicting the long-term strategic impact of such a strike. A strike might delay by three years Iran's attainment of its goal—but at the cost of further embittering the regime and its people. Iran's intentions when it did get the bomb would be all the more hostile.
Bear this in mind in the coming months as the war talk against Iran intensifies. Bush and the people around him may be tempted to strike. But if they do, the result could make our current difficulties in Iraq look minor by comparison.
