They suffered many losses and run back to Pakistan to regroup, sat there for over 15 years and when the US began to withdraw they pretty much took Afghanistan back without a fight. To finish them off the US had to invade Pakistan or make it so costly for them to support the Taliban that they would have to give them up and they weren’t willing to do that for obvious reasons.
