We will have to agree to disagree on Israel’s long term viability without the support of the US. Perhaps if Iran was defeated but so far that has not happened.

look again at iran's peace terms - there's nothing in them about destroying israel, and this is Iran shooting its best shot.

Israel might not be able to contjnue with the genocide, expand its borders, or be a hegemon without US support, but the other powers around aren't calling to destory it or using the lack of its destruction as a bargaining chip. Israel's continued existence is pretty secured unless it falls apart from within
