Theres a whole lot of people that think this is all still The War against Afghanistan. When Obama declares it is over, many of his supporters will say he 'ended' the war with Afghanistan. We need to be quite clear about what is 'ending'. What is ending is sustained combat ops against an enemy that while ousted and hiding in caves, still represents a threat.
Personally...I think Bush made a mistake in post war ops in both countries and Obama simply continued those mistakes. The ROE in the last 6 years has been disastrous. I guess its better that we just 'quit' but its not going to make anything better (except maybe making fewer of our troops in theater and vulnerable).
