To be fair, it only "literally changed the entire world" because america refused any other outcome, massively overreacted and threw a temper-tantrum, bombing the hell out of people who had nothing to do with it, and forcing what was essentially their own problem down everyone else's throat.
It's like if my house were broken into, and I said that the event "literally changed the entire neighbourhood" because I started gunning down passersby, throwing hand-grenades through my neighbours' kitchen windows, and siphoning petrol out of their cars.
