A Promise Israel Would Expect Us To Keep

Amos Yadlin, former head of Israeli military security and one of the pilots who flew F-16s in the strike against an Iraqi reactor in 1981, summarizes the stakes in next week's U.S.-Israel summit:

Asking Israel’s leaders to abide by America’s timetable, and hence allowing Israel’s window of opportunity to be closed, is to make Washington a de facto proxy for Israel’s security — a tremendous leap of faith for Israelis faced with a looming Iranian bomb. It doesn’t help when American officials warn Israel against acting without clarifying what America intends to do once its own red lines are crossed.

Mr. Obama will therefore have to shift the Israeli defense establishment’s thinking from a focus on the “zone of immunity” to a “zone of trust.” What is needed is an ironclad American assurance that if Israel refrains from acting in its own window of opportunity — and all other options have failed to halt Tehran’s nuclear quest — Washington will act to prevent a nuclear Iran while it is still within its power to do so.

I hope Mr. Obama will make this clear. If he does not, Israeli leaders may well choose to act while they still can.
