The attacks of September 11 were a spectacular success. Is there any other honest interpretation? They were a success not because of the Americans they killed that day, but because we chose to spend the next decade mired in hopeless, counterproductive global wars that cost us trillions of dollars and killed thousands more Americans and hundreds of thousands of innocent civilians. Terrorists wanted to show the world that we were brutal and unjust, and we did our best to help them do that. Terrorists wanted a war, and we gave them one. And we lost. We lost by giving them the stupid, fearful, angry response that they wanted.
