How Much Does the Terror Confession Change Our View of Terror?

I assume that I was not the only person who was astounded when some details of Khalid Sheik Mohammed’s confession were made public the other day. Although there are many reasons to doubt the veracity of his claims, if he is responsible for even half of what he says, how much does it change the American perception of the ongoing Islamic threat against the U.S. and, subsequently, the U.S. war on terror? That is, if so many of the most damaging terrorist acts of the past decade were conceived and/or shepherded and/or financed by one man, does the idea of a huge worldwide army of American-hating Islamic fundamentalists begin to seem out of date, or at least out of focus? Does it seem a bit like living in a city with a whole lot of violent crime and then finding out that 80% of it was being perpetrated, if indirectly, by one big mob boss? This would hardly diminish the losses and the atrocities, of course, but how much does it change the apocalyptic perception that so many Americans seem to hold?
