So here's a question that I've been wrestling with lately: With all these reports about the bungling of U.S. intelligence, and the C.I.A.'s relying on bogus informants with names like "Curveball" or "Knucklehead" or whatever, why have there been no terrorist attacks in the U.S. since 9/11? I've got my own pet theory about what's produced this period of calm - and, more important, why it may be coming to an end.
Let's start with the facts. Despite all the code reds and code oranges we've been subjected to by the Department of Homeland Security, and despite the mountain of newspaper articles about how underprotected our ports and borders are, the fact is that not only has there not been another 9/11, but there has not even been a serious failed attempt that we know of.
