It does not necessarily matter to AIPAC if you preach "New World Order/Illuminati" conspiracy theories involving "international bankers," a classic coded anti-Semitic trope. Nor does it necessarily matter to them if the rhetoric you have spewed about the Holocaust sounds like a Christian version of Mahmoud Ahmadenijad. AIPAC doesn't even necessarily care that you've lionized Yigal Amir, the assassin of Israeli Prime Minister Yitzhak Rabin. What matters more to AIPAC and its allies -- all that matters perhaps -- is that you back the hardline Israeli government without reservation, support the institutionalized dehumanization of Palestinians and offer crucial moral support for the illegal usurpation of Palestinian land. Oh, and it doesn't hurt that you lust for war with Iran.
It should come as no surprise then that an anti-Semitic Holocaust apologist like Pastor John Hagee was invited to AIPAC, and was given a raucous ovation. As I reported for the Nation last year, through his new lobbying organization, Christians United for Israel, Hagee is emerging as the most influential leader of the Christian Zionist movement, which has bolstered the Israeli right with the grassroots muscle of the evangelical right. I go on to explain in detail that Hagee is a dangerous crackpot whose stated desire is to see Israel engage in an apocalyptic nuclear war with Iran.
Go see Max explain it in detail. Video and many links.
All I know is that when you get a conglomerate of disparate right-wing warmongers together to do evil shit in the Middle East, ya got big trouble.
