Further, they WERE beaten, in a mere two "Mission Accomplished" weeks.
Problem with that is that they were allowed to run off and stay in Pakistan, where to date the majority of them reside, being a proxy army of that country.
Not only have we done little to alter that, even Captain Cheetos's Tweets haven't stopped US funding of the artificial state of Pakistan, which channels a nice allowance of that into the Taliban.
Also, the USSR exited in 1989, and the Taliban came into being 1994.
