What power do you think he has? You do realize that the Israelis do not need to rely on us for military aid, correct? You also do realize that there are a couple other world powers who are not allied with the US who would be very happy to cozy up to Israel which means that they would have much more power and influence in the Middle East because at that point it would be Israel and Iran.

I think you must be at least somewhat naive about just how right wing and authoritarian the Israeli government is.
