maybe some Afghans wanted to use the US to destroy the hospital?
An interesting postulate, deptrai.
The problem is that it beggars belief that the Afghans could have expected the US forces to do anything so monstrous as to "raze" the province's only hospital.
The splashback against US imperial aggression was so predictable and the embarrassment would so predictably go to the very highest level that surely the Afghans could not have expected the attackers to fall for such a trick.
As ever, I think the cockup theory is vastly more plausible than any "conspiracy" theory. It was just the Americans doing what the Americans do. Not much different from bombing Sudan's only medicine factory or a baby milk factory in Baghdad or shooting down an Airbus or any of a hundred other atrocities.
