I enjoy your posts, and I've learned a lot from them over the years; but honestly I think you should probably just pull your pants up here. Yes, the PMC in general and most governments are going to rationalise co-operating with the Taliban govt of Afghanistan. For reasons, as you say, none of them good.
I don't think the answer is othering and monstering, as
Brainaddict pointed out, it misses the point that they won. Against NATO, and the US and UK in particular. In the main because of corruption that NATO supported, for reasons (none of them good).
So, to see it from a less Eurocentric point .. what may have happened, is that lots of Afghans preferred a harsh government they understand but see as honest, if brutal (and has there ever been a time in Afghanistan that life was not brutal for most people?) .. over a foreign-backed, corrupt government that allowed NATO (and the US and UK in particular) to bomb their shit.

kids.
