If Israel misses its window of opportunity to act, such a lapse would violate a central tenet of its own defense doctrine — that Israel cannot depend on any external power to deal with existential security threats — thereby making that option unthinkable. Once Israeli intelligence agencies and senior military command levels conclude that the clock has struck one minute to midnight, no amount of pressure from allies will succeed in dissuading it from acting in self-preservation.
A military strike would not be a goal in itself, as Iran could go right back to reactivating its program, but it would be a last resort designed to accomplish what years of talks could not: to push Iran back from the nuclear brink.
Israel’s strike capabilities remain a closely guarded secret, but according to international media reports, the Israel Air Force has more than 100 F15i and F16i fighter jets that can fly to Iran and return without the need to refuel, as well as, for other jets, advanced midair refueling capabilities that would allow them to strike multiple Iranian targets. According to the reports, Israel also possesses long-range Jericho ground-to-ground missiles.
Any strike, moreover, would be unimaginable without the Israel Defense Force’s advanced electronic warfare units.
In the event that Iran orders its Lebanese proxy, Hezbollah to retaliate with tens of thousands of rockets and missiles on the Israeli home front, Israel could respond with devastating air force strikes using new weapons systems, and a lightning ground invasion of southern Lebanon to extinguish quickly the rocket attacks and leave Hezbollah on the ropes.
No one in Israel seeks war, and few dispute that a diplomatic solution that can really freeze the threat from Tehran is the most desired outcome.
But so far, beyond empty gestures, Iran has given no indication that it is prepared to give up its program, and time is running out.
