I seem to recall the Israelis having to play a Cold War game of gaining support from the Soviets or the Americans. They would "befriend" one side to get concessions from the other. In order to survive, Israel had to deal back and forth. Any aid gained from the US was only after either heavy Jewish lobbying OR the Americans fearing Israel turns close to the Soviets. It was not like the US backed Israel the entire time and inundated them with weapons and cash.
