Here's something to be thankful for today: counterterrorism. If there is any real lesson for us from the attacks in Bombay which are just now ending, it is that it could have been us. There's nothing unique about Bombay that made it a good target; this sort of attack could have been successful in any American city. We know they want to, but apparently they haven't been able to. For seven years, what we considered inevitable on September 12 hasn't occurred. This is not by coincidence. For all the pointless waste and excess of the Department of Homeland Security, something is clearly working, and for that I am thankful.
