All true, but it would take just a few nukes to entirely wipe Israel off the map.
The Islamic World with a billion people can take 300 nukes and survive, I doubt Israel can take 3 nukes and stay together as a nation state.
Samson option and I doubt anybody around them would stay together as a nation state either.
Heads of a bunch of snakes would be cut off to boot.
Not a good outcome for anybody, but that is the purpose of the *MAD* deterrent.
