Not good for anyone. This will hurt Iran, because the US will be stupid enough to defend Israel. This will hurt Palestinians, because the US will send more shit to Israel that will be used against Palestinians. This will hurt Israeli terrorists (slightly). This will hurt Israeli civilians who oppose the genocide.
Not good.
