Daniel Pipes lists here all the excuses people have dreamed up to keep from acknowledging that the various attacks on New York City (and the rest of the United States) since 9/11 have been the result of jihadist ideology and action.
And Barry Rubin speculates on reactions in that vein to other crises, from the Revolutionary War to the attack on Pearl Harbor.
My analysis of the problem: "Denial is not a river in Africa." We won't get anywhere until we acknowledge publicly that Islamism is the problem here. Period. People are afraid to admit the truth, either because it pulverizes their pet theories, or because they'd have to realize just what kind of threat we face.
So imagine the gratification of hearing the CNN news anchor this morning say that she'd put together all the info on these attacks, looking for the common denominator and discovered that it was - can you believe it - Islamic fundamentalism. CNN no less! Wow!
