I'm pretty sure Bush, and his supporters, have acknowledged than things other than hate contribute to terrorism in the past. Unlike his detractors, however, he (and we) don't think those factors serve as an excuse.
In regard to the other matter Bush accepted responsibility for the failures of the federal government in response to Katrina (which was discussed on that thread, in fact), not the failures of the state or local governments. I don't believe that anyone here has ever argued the federal government was 100% failure free in the response to Katrina, only that other factors also contributed to the situation, many of which were out of Bush's control.
