Most certainly. One of the big challenges we have anywhere in the world where we're operating is the movement of illegal arms. This is not a new, unique problem in Afghanistan. It is everywhere.
Through the intelligence forces of most NATO nations and certainly within region south, we are working together tightly to understand when and where these weapons will come in. So we have to remain vigilant, and we have remained extremely vigilant.
I really can't get into the specifics of some of the successes we've had in preventing other arms from coming. I think this would be a great question when General Hillier comes. He's just recently returned from a trip to Afghanistan and he was in Pakistan and met all his counterparts over there. They had a very good dialogue by trying to say okay, let's stop yelling at one another and let's work together to solve this problem.
Certainly from our perspective we are a lot more upbeat on what's occurring up and down that border. Both from a partnership with Pakistan and our own ISAF forces, there is more effort being applied to understand what is going on in the border region.
For example, a minor example, the Americans have helped the Pakistanis build some fencing in certain areas, in really known routes, so that we can have better control and see what's going on. Over time, certainly if you'd asked me six months or seven months ago—We have made progress in that area, but we need to remain vigilant.
