Most worrisome, I think, is the danger that a crisis between Israel and Iran would escalate out of control. Given the history of mistrust and the absence of communication, some war planner on one side or the other might guess that a nuclear attack was imminent, and decide to go first.
“You would have a very unstable deterrent environment between Israel and Iran, simply because these are two states that tend to view each other in existential terms,” said Ray Takeyh, an Iranian-American Middle East scholar at the Council on Foreign Relations, who is not an advocate of containment. Against this fear, history suggests that nuclear weapons make even aggressive countries more cautious. Before their first nuclear tests, India and Pakistan fought three serious conventional wars. Since getting their nukes they have bristled at each other across a long, heavily armed border, but no dispute has risen to an outright war.
At the end of this theoretical exercise, we have two awful choices with unpredictable consequences. After immersing myself in the expert thinking on both sides, I think that, forced to choose, I would swallow hard and take the risks of a nuclear Iran over the gamble of a pre-emptive war. My view may be colored by a bit of post-Iraq syndrome.
