After limited sanctions, Iran will talk. Who knows where it might go? The regime would not survive serious sanctions on oil exports, which is the next step, so they have a big interest in an acceptable solution. All the cards are in the hands of the big players, not the mullahs. Nothing is off the table, including oil sanctions or even military strikes. Israel is more of a hindrance than a help with its bellicose warmongering. It is doubtful the IAF could do anything militarily anyway, lacking aircraft range and ordnance. Best if Israel concentrates its energies on granting an early and fair 2-state solution to Palestine, that would remove one of the biggest provocations in the ME. Next, it might care to join the NPT as a responsible nation, which would remove another. The chances of either happening are of course zero, as Bibi tries to shift the spotlight from Israel to ANYTHING else and parades on the stage with big talk for his domestic supporters.
