The U.S. does not care about the Israelis. They only care what the Israelis do for them.
Like Biden famously said (before his dementia) “If Israel didn’t exist we would have to create one”
The U.S. funding the Israeli military is only to accomplish the U.S. goals- to secure hegemony in the region and other imperialist agendas, currently to encroach on Eurasia for their resources and market.
