That's a good question. The potential, because of the media profile of what happened on September 13, is that the impression could be given that all hell is breaking loose in Kabul. The fact of the matter is that the number of security incidents that have occurred in Kabul over time are on a steady decrease. What we saw last week was certainly a well-planned and determined effort by people who are prepared to die to do what they're doing.
I would just highlight that Kabul is a city of five million people. It's a developed urban environment. This is a very difficult environment in which to operate. The significant thing, from my perspective as a military officer, last week was the response that was furnished. It was Afghan-led. It took approximately 20 hours or so before the thing was cleaned up. But if you think about what happened in Mumbai a few years ago, by comparison, these things happen, and it took a matter of days for that event to be secured.
So the Afghan forces will do things their way, and in this case, certainly as we're observing this, we are seeing a lot of positive signs, notwithstanding the seriousness of what occurred. I assure you that the people on the ground are studying this very carefully and taking the necessary measures to pre-empt any future ones--not to say it won't happen, but this is something that is continually reviewed, continually studied, and we're very, very diligent in this area.
