Feels like another issue where one's impression of what is happening is at least partly decided by the date you think it started from: some on twitter are pointing out that the Taliban were firstly armed and developed when USA were supporting them to fight back against Soviets.

For all the intervening UK and USA has done in other nations (justified or not) what are the examples where the exit strategy has been pulled off well instead of just creating another mess needing attention in the next decade?
