O is getting us out.
More or less "responsibly"
I know that is subject to interpretation
Probably we could have just packed up and left, vs. "finishing the job and leaving the Afghans capable of securing their own country", and in a year or two, no one would actually be able to tell which we had done.
Just packing up would have been diplomatically, and politically, impossible.
That's just how that ball bounces
The trick is avoiding the shoot from the hip stupidity that gets us into these things to begin with.
