The tragedy of this makes me even angrier about Iraq, which was a huge distraction and which sullied the idea of any Western intervention for a generation. Blair and Bush have lots to answer for on this. For Bush, it was all about finishing his dad's work. For Blair, it was a delusional messiah complex. For lots of people it was about making lots of money. There was no external threat from Iraq whereas Afghanistan was and soon will be again a breeding ground for extremism.
Afghanistan was a UN mission and whilst so much money has been spent on it, there was a tangible benefit to it and I think if it had been a priority for the first decade instead of Iraq, they may have managed to create some substance to the new way of life. What's happened in terms of the speed at which the Taliban have taken back control is incredible.
There will be girls in Afghanistan who remember nothing but the western-backed regime. Going to school, seeing females in high profile positions (journalists, politicians etc).. overnight that's all changing and it's horrifying.
Politically, I assume Biden thought (same as Trump) that voters in rust belt swing states just wanted to see an end to American interventionist foreign policy with the somewhat simplistic "let's spend the money here instead" message. The same message would resonate here in Brexit-voting towns and it's why the Tories cut the foreign aid budget. I'd be interested to know how the pictures we've seen over the past 48 hours are being received in places like Pennsylvania.
