Did you read "The Ezekial Option?"
I remember when Israel was almost overrun in 1973 and Golda Meier was almost ready to pull out the nuclear weapons, but at the last minute, things turned around with the military defenses, so they pulled them back.
The only thing about that ... is as I said before ... Prime Minister Benjamin Netanyahu knows what he needs to do to accommodate the world powers and at the same time, work towards the TWO-STATE SOLUTION that he has affirmed repeatedly that he is working towards, per Bar-Ilan.
I wouldn’t worry about those kinds of theoretical situations which would be created by a “crazy Israeli government” ... LOL ... because Prime Minister Benjamin Netanyahu is VERY PRAGMATIC in how he governs and protects Israel!
