I get the impression that the last 20 years was a waste of life and resources because everything they were trying to do didn't produce lasting fruits. Afghanistan is returning to the way it was before. Quite a lot of British foreign aid went to Afghanistan, perhaps they should just invest all the money on themselves next time.
Now I wonder what the neighbouring countries think of the situation. They share a border with Iran and Pakistan I think. I wonder what those two countries think of the Taliban annexation.
