The biggest phase shift will be when people no longer see the US as the all powerful Superpower (looking at you Tankies), but just an annoying and belligerent dick way past it's heyday and falling apart....just like Russia.
Europe can do without the US, Asia can do without the US, it's not a superpower any more, it's a divorced male living in a racing car bed. There's a whole other world aside from the US, let's move on.
