Sounds like those Iranians, Arabs, and others who claim that the Jews in the WTC had advance warning given to them by Mossad. 

True. Interestingly, accroding to the NYT, and as is mentioned in this article (there's also a Fox News video report out there about it with Bret Hume that I have seen as well), the only people who were arrested on suspicion of having knowledge of / being somehow involved with the events on 9/11 in the U.S. in the immediate aftermath were a few Israeli citizens. 

Now, do I believe that Israel was behind 9/11? Absolutely not. Muslim jihadists (Al-Qaeda) were behind 9/11. But do I believe that Israel knew (possibly) that something big was going to happen (perhaps not the details), and didn't share that intelligence with the U.S.? I do. There are a lot of credible sources in the intelligence community that have said so. After all, Israel, just like any other country in the world, plays dirty and sneaky when it comes to its own interests.

I'll be the last standing person on Nature's Green Earth to defend anyhting moslem, but the nutcase right wing party and their conservative clan in the US are a strange bunch. Sooner or later, they will need to crawl out of the 50's and realize that things have changed!
