My husband was given, (from a Jewish client who despises Bush,) an article written by John Loftus, published in the Aug. issue of the Jewish Community News. It is really lenghty but the upshot is that the majority of Jews believe that in 1920 an organization known as the Muslim Brotherhood which is the original AQ and Arab Nazis was working with Hitler. It became the official policy of the The Third Reich to secretly develop the Muslim Brotherhood as the fifth Parliament, an army inside Egypt. After WWII they moved to Saudi Arabia at which time BinLaden became interested. They also believe the CIA is an arm of this secret society which hates Jews. On top of it all they believe Bush 41 and 43 are also involved and support the Muslim Brotherhood.
I sincerely doubt that a "majority of Jews" have ever even heard of this particular conspiracy theory.
