"As to how Jones could have signed the statement below, let me make clear that neither he nor I, who also signed the statement, signed something accusing Bush of being directly involved in 9/11. I did authorize my name to be used to call for an investigation of the claims of those who deny the official story of 9/11.

I am now and was then an agnostic about what actually happened to make 9/11 possible, but do agree with those who say that there are enough inconsistencies and problems with the official story to warrant an impartial investigation by people not connected to the government of the US and not bound by political considerations. I think that such an investigation would be a great advantage to everyone.

Anyone care to reply to this?

To the editor:

Tikkun's publication of David Ray Griffin's article about 9/11 --
http://www.tikkun.org/magazine/tik0703/frontpage/empire911 -- is both
courageous and detrimental. It is courageous because there is a lot
of good evidence for Cheney/Bush complicity. Close US allies,
including France, Germany, Israel, Jordan, Russia and others provided
specific warnings that 9/11 was imminent. At least five FBI
investigations were undermined just before the attacks. During 9/11,
numerous war game exercises seem to have confused the air defenses or
moved fighter planes too far away to intercept the hijacked planes.
And the National Reconnaissance Office (which operates spy
satellites) was conducting a "plane into building" exercise at the
same time as actual events. In short, 9/11 was allowed to happen
and probably was provided technical assistance to make sure that it
happened -- since the "new Pearl Harbor" was needed to provide the
excuse to seize the Middle East oil fields as we pass the global peak
of petroleum production. That is what the "Cheney energy plan" is
really about.

The Jewish Daily Forward has an article on Rabbi Michael Lerner and his contribution to David Ray Griffin's recent collection:

A 9/11 Gov’t Conspiracy? ‘I Wouldn’t Be Surprised,’ Says Tikkun Editor

Rabbi Michael Lerner, the longtime activist and editor of Tikkun magazine, has published an essay saying he is open to the possibility that the American government may have been behind the September 11 terrorist attacks.

“I would not be surprised to learn that some branch of our government conspired either actively to promote or passively to allow the attack on 9/11,” Lerner wrote in an essay published in the new book, “9/11 and American Empire: Christians, Jews, and Muslims Speak Out.” Lerner added that he would also not be surprised if it turned out that the attacks were not the result of a government conspiracy.
