I hear you, there may be room for some doubt about what else he might say but I don't understand him to be criticizing Bush in this interview. I mean, let's face it, if Keyes thought Bush was responsible for 9-11, he wouldn't have endorsed Bush for reelection in 2004.
I think Keyes has been very supportive of Bush's policies and I never could understand what all of the arguing was about.
Some people see his criticisms as being disloyal. The question is, to what should one be loyal? Everyone has the right to answer that for themselves.
I think Keyes has taken a sensible approach in his general support of the Bush administration.
