Just a quick blurb from the best blog on the Internet:
Now, it's crucial to note that there isn't a closely organized Russia-Israel-U.S. Jewish Mafia-with-a-capital-M. There are merely a number of opportunists who tend, for reasons of family ties, educational connections, personal style, ethnic solidarity (we all hang together or we all hang separately), and personal comfort level, to do illegal business with each other rather than with people from other ethnic groups.
Over time, these opportunists proved more successful than their competitors on a per capita, for a variety of reasons -- brains, experience, the existence of Israel as a refuge from arrest, and ties to the business, media and think tank worlds in America generating financial and political capital.
But one huge advantage has been that they've achieved what the Italian-American Civil Rights League attempted and failed at: freedom from criticism.
The previous, and far more competent, owner of this blog, tried to keep his identity secret, and still, for some still unknown reason, had to delete the entire blog without leaving so much as a clue why. I can think of no other political criticism the consequences for which are so high.
This is wrong. There is absolutely nothing wrong with critiquing US policy in the middle east. Those who are trying to claim otherwise are just hiding behind false claims of anti-semitism in order to avoid real debate on the issue.
Unfortunately, quite often it works.
