The real villain here is the left. Israel has been abandoned and villified even by many American Jews because of left wing propoganda. The left supports radical moslems against the U.S. and Israel, they blame Israel for terrorism.

The left promotes class, ethnic, and racial divisions. All their supposed support for one group (blacks, Islam, women, etc.) becomes hatred for other groups (whites, males, Jews, Christians, etc.) that ends up being the worst possible racism, anti-semitism, and intolerance.

What you describe is a part of the phenomenon that libertarian economist Arnold Kling calls "Folk Marxism": http://www.freerepublic.com/focus/f-news/1563376/posts

All other explanations of the Left's betrayal of Israel were not satisfactory logical to me until I read that article.
