If anything, I think all of the NATO countries should stay committed in the short to medium term in the roles they're playing in Afghanistan. They should continue to do the security front. A withdrawal timetable, without maintaining some stability, is not helpful. It would be looked at, in my opinion, as a great strategic win for the Taliban. That being said, there's a lot we can do to improve the effectiveness of our military operations strategically, which is to continue to explain, communicate, and follow up military wins with civilian wins.
