Trump wanted to end the war in Afghanistan, but couldn't quite bring himself to do it, because he wanted to end it in a way that made him look good, or at least made him look smarter than the foreign policy establishment. Biden actually ended it, even though it was chaotic and disorderly, in part because of steps that Trump had taken.

I would also add the Biden didn't really get any credit for ending the "forever wars" because Ukraine and Gaza make it feel like we're still at war, even though we don't have troops in those conflicts.
