They have effectively deplatformed Europe, South America, the Middle East and Asia, put anyone but China within second reach from a mass data collection perspective, and expanded the economic hegemony of the US more deeply and completely than the military ever could.
The US is now on the verge of the second great breakthrough of mass automation of that data, intelligence and action. I am honestly shocked that this third stage of American Dominance has not be countered by any other nation save China, and even they're only defensively. America's global brain drain might have been the single most effective strategy that the planet has seen so far...
The only question is if the rest of the world is going to wake up and counter this.
