Read carefully an enemy of Israel, Noam Chomsky, on Israel American relationship. Your will find a logical response to your querries. American imperialist interests in the Middle East are protected by Israel. Despite minor or major misencounters, Israel is cheaper and much more effective than any other alternative. Of course that N Chomsky would like to see a u-turn in American Foreign policy, but he understands that this is impossible. America is imperialist by definition, and will never change Israel for Hizabalah Hammas and Iran. Why? 1) Because it is not strategically logical. 2) Because Israel is not S.Vietnam and have lots of friends in Washington if you know what I mean.
