You are letting your justified anger towards that one group of leftist globalist Jews color your perceptions of Israel. Israel is not globaist, and is not an enemy of the US. Globalism is.
Perhaps Israel is anti-globalist in a very significant way. Globalism as a one world government would require some very large acts of imperialism to shove all peoples under one roof. Israel was one of the first victories of the postwar movement to decolonization and the breaking up of the European empires. India became free earlier.
If Israel gets significantly weakened, it could begin a movement towards recolonization under a new imperium. All countries small in either size or population could be the first at initial risk.
