We won WWII 71 years ago, and we still have 53,000 troops stationed there.
There are two correct ways to continue after a successful military action: Plan for a very long stay to enforce the changes (Europe, Japan), or leave immediately and warn the new government to be good or they get toppled too. Intermediate options, staying for just a few years (Iraq, Afghanistan), are a complete waste.
I would have wiped out the scum before the Calendar hit 2002, then left. If you gotta come back later, so be it.
Instead it’s 2016, we never left and yet the Taliban still GD exists? What the hell have we been doing over there besides wasting money and American lives?
