Force is not inevitable. Diplomacy is still the desired means. Pressure is an element of the means.

You don't have any communication between the Israelis and the Iranians. You have all sorts of local triggers for conflict. Having countries act on a hair trigger - where they can't afford to be second to strike - the potential for a miscalculation or a nuclear war through inadvertence is simply too high.

I wouldn't discount the possibility that the Israelis would act if they came to the conclusion that basically the world was prepared to live with Iran with nuclear weapons. They certainly have the capability by themselves to set back the Iranian nuclear program.

Overwhelmingly, Israel's political and military establishment want the rest of the world to act diplomatically or otherwise to stop Iran. But if that doesn't happen, then the impulse toward the use of force will become quite strong.
