Answer:
Step-by-step explanation:
Considering that they should never have gone in in the first place, it's about time that they pulled out. I saw a cartoon the other day of an Afghan standing beside the road looking at all the head gear of those trying to conquer the region -- Rome, Russia, one more I can't remember and The US. It's quite a list. History should have told America to stay out.
If Russia couldn't do it, (and she's much closer to Afghanistan than America is) then it should have been a warning not to try.
