The Iranians, of course, never cease denying that they intend to build a nuclear arsenal, and yet in the same breath they openly tell us what they intend to do with it. Their first priority, as repeatedly and unequivocally announced by their president, Mahmoud Ahmadinejad, is to “wipe Israel off the map”—a feat that could not be accomplished by conventional weapons alone.

But Ahmadinejad’s ambitions are not confined to the destruction of Israel. He also wishes to dominate the greater Middle East, and thereby to control the oilfields of the region and the flow of oil out of it through the Persian Gulf. If he acquired a nuclear capability, he would not even have to use it in order to put all this within his reach. Intimidation and blackmail by themselves would do the trick.

Nor are Ahmadinejad’s ambitions merely regional in scope. He has a larger dream of extending the power and influence of Islam throughout Europe, and this too he hopes to accomplish by playing on the fear that resistance to Iran would lead to a nuclear war. And then, finally, comes the largest dream of all: what Ahmadinejad does not shrink from describing as “a world without America.” Demented though he may be, I doubt that Ahmadinejad is so crazy as to imagine that he could wipe America off the map even if he had nuclear weapons. But what he probably does envisage is a diminution of the American will to oppose him: that is, if not a world without America, he will settle, at least in the short run, for a world without much American influence.
