Isn't that weasel speak for "the Jews are to blame?" His rhetoric is awfully close to what you normally hear from the Jihadists, Klansmen and Neo-Nazi pinheads regarding the Jews.
He also argued that the terrorists who carried out the attacks "manifested the courage of their convictions" and "when you push people around, some people push back. There is justice in such symmetry."
Jihad, anyone?
