I can only give you a personal answer, I guess: it's a reason for us to work harder and to maintain the effort that we've invested in the country.
It is showing progress. I would actually argue that if you look at Afghanistan today, at Kandahar, and compare it to where it was, say, two years ago, you'll see a big difference.
Again, to quote from a survey that was conducted by the Asia Foundation--you can find it on the Internet as well as within a NATO report--Afghans actually, by the vast majority of 96%, do not want a return to the previous days under the Taliban regime. More than 80% are actually satisfied with the current government, no matter how imperfect it is.
So I think we are making progress, but it's slow.
