If you want to be mad at someone, make it the power players who were/are using the country as a battleground for their personal projects: George W Bush and his hawks and Donald J Trump and his moronic minions on the American side, doubtlessly the Russians (for some revenge), India and Pakistan fighting a proxy war and a whole lot of extremely unsavoury people from the Persian Gulf region financing and supporting the Taliban directly. Take your pick, I’m sure my list is far too short.I am angry at the Afghans. We trained them supplied with guns. They didn't fight the Taliban they joined them.
The Afghan people are just caught in the middle of it and hardly know what’s hitting them on any given day.
