It will never happen and they know it, thus the reason they do as they please. While a good chunk of the western world will condemn them if some other Arab nation decided to put boots on the ground those same western nations would likely send their own boots. At least the US likely would and then it’s game over.

Add to the fact that even WITHOUT direct western involvement there’s no a single Arab nation or anyone with a grudge against Israel that could mass an army of any threat to them or they would have done it by now.

They’re that dorky little pipsqueek from school that had tough older brothers and a father with influence so people allowed the little turd to get away with whatever they wanted. No one is going to put Israel in check and Israel themselves count on this fact.
