I think the road map for all of us is the London Conference on Afghanistan compact that was put in place, with numerous benchmarks that include much of what we're discussing here around the border. Prior to that, there was another compact that essentially set out various broader themes of good governance, a return to some of the very principles of democracy itself, the development side, and the issues related to sovereignty itself--that is, the Afghan people having full control over their entire country. The south is where the majority of the difficulties still exist. That's the more general answer.
The more specific answer is that in our embassy in Kabul and our high commission in Islamabad we have regular contacts, and our diplomats there are engaged with government officials in both countries. We have other political contacts, which I've referred to, and we have these international fora that also provide for the checks in the box as to what we have done, what we can see, in concrete terms, to measure work that's supposed to be under way at the border.
Are we still seeing the same degree of movement? Our military information coming from the field is the most direct answer to your question, where we can say, “Well, we've been told there are soldiers at the border, that there is construction of certain checkpoints and fences, that there is aerial surveillance; show us that this is actually happening.” We can't, unfortunately, just take people at their word when they say they're doing something in this area, when we know that the insurgency is continuing, and in some cases escalating.
