I would say there is an understanding that there are a lot of problems in Afghanistan; I don't think we'd be there if there weren't. As a result of that, we entered into the December 2005 MOU. If we thought there were no problems, we wouldn't have done that. We have consistently ratcheted up what we're doing in order to try to minimize the risk and to make sure there is not a substantial risk.
