Preventing a Nuclear Iran, Peacefully

The debate over how to handle Iran’s nuclear program is notable for its gloom and doom. Many people assume that Israel must choose between letting Iran develop nuclear weapons or attacking before it gets the bomb. But this is a false choice. There is a third option: working toward a nuclear weapons-free zone in the Middle East. And it is more feasible than most assume.

Attacking Iran might set its nuclear program back a few years, but it will most likely encourage Iran to aggressively seek — and probably develop — nuclear weapons. Slowing Iran down has some value, but the costs are high and the risks even greater. Iran would almost certainly retaliate, leading to all-out war at a time when Israel is still at odds with various Arab countries, and its relations with Turkey are tense.

Many hawks who argue for war believe that Iran poses an “existential threat” to Israel. They assume Iran is insensitive to the logic of nuclear deterrence and would be prepared to use nuclear weapons without fear of the consequences (which could include killing millions of Palestinians and the loss of millions of Iranian civilians from an inevitable Israeli retaliation). And even if Israel strikes, Iran is still likely to acquire nuclear weapons eventually and would then be even more inclined to use them.
