I am aware that it was some of the US military. The US would use all available forces and armaments to protect order within the nation in the event of a revolution. You also conveniently glossed over the vast difference of the Afghani police forces and the US local and state police as well as the National Guard and reserves.
Lastly, I didn’t call you an idiot. I said you’re being childish, because another person on the internet has an educated opinion that differs from your own, and you address it by resorting to name-calling. Good day.
