I wouldn't call it a job of the US. The US took part in it for money, but that's it.
Just as with the history of the world wars — for America, everyone but its clear enemy have been and are nonexistent. Everything that has happened/happens with abuse of power and with the US happening to go along for some selfish reasons, had been/was the plan of the US all along, done by no one but US. Awful self-centeredness that probably has led to all the paranoia about being constantly under attack.
