yea, but remember Japan/Korea, and many EU are still US ally. Trump is an exception, he piss off alot countries, including allies. but soon or later he will get replace with someone who could be more capable. what happen if that person decide to get EU/Japan and other to pressure China on trade as united front. At the end of day EU/Japan/Skorea/Aussies are still US ally, and they are also not satisfy with China trading.What many people don't realise is that China+Japan+Korea+Taiwan+Southeast Asia already has a higher combined GDP than US+Canada+Mexico. The EU is larger than the US, too. The world is no longer a polar world where America is the sole economic power or hegemony. To ask the world to isolate is a mission impossible for the US, as it would be punching way above its weight.
You just simply can't isolate the largest trading nation by far in the world, the nation with more than 1/5 of the world's total population.
