You should read this comprehensive article, “The Israel Lobby” by John Mearsheimer and Stephen Walt. Unless something drastic happens soon, this tiny group of American Jewish plutocrats, and the staffs of lobbyists they have working for them, are going to lead us all into World War Three. American policies towards the Middle East fostered by the Lobby will inevitably eventually push hard against the energy security of Asia, and when China sees there is no way out the shit will hit the fan (good article here on how the American stupidity of using nuclear politics to cause conflict between India and Pakistan ties in to the clumsy attempts to stop Asian access to Iranian gas, which of course is a policy dictated by the Lobby).
The funny thing is that the policies the Lobby forces on the United States don’t even really benefit Israel. It has become a pure power thing for them, as they flatter themselves seeing how much they can push American politicians around. The choices are becoming quite stark: either what amounts to a kind of civil war in American politics, or World War Three.
