"They'll be surrounded by very angry nations who will want them to disappear"

That is a pre-existing condition to Oct 7th. It is why they will continue to be supplied with weapons for defensive purposes, even if reduced on the offensive front.

No government wants Israel to not have traditional defenses. They are a potential nuclear threat.

Israel is estimated as of a few years ago to have about 1/3rd the amount of nuclear weapons of China. Now it is only about 1/5th, but that is only because China is rapidly building a nuclear arsenal; pre-covid they had about 300-350 nukes, 2 years ago they had 400, now China is up to 500. Estimated to have 1500 nukes in ~10 years.

I'm not trying to talk about China, more put on the scale that their tiny country has a massive nuclear capability in comparison to such a large country as China in modern times. In an existential threat, I wouldn't be surprised about them using them, as they are the only country in that area of the world potentially with a nuclear arsenal.

This is more informational for those that do not know that Israel is considered a nuclear power:
