Why are we still leading missions, instead of supporting Afghans conduct them?

[Bob's World]

Will they negotiate a settlement and share governance, or will they fight until someone wins, with the winner taking complete control and stomping the loser?

Given recent history and the prevailing political culture, which is more likely?

I don't know. I just know what will happen if we only support one side enough to create an unsustainable "decent interval" and then leave.

Better to try what might not work but creates a chance at an enduring stability than to try what we know is unlikely to create an enduring stability but that might create a narrow window of "success" that we can withdraw through.
