The US still has a potentially massive coalition that would be compelled to follow.
China would be ended in short order.
The chicoms most certainly exist on borrowed time.
FREE HONG KONG - FREE CHINA!
China has friends in low places - North Korea, Iran, Russia and Pakistan.
Then you have two of the EU’s biggest Marxists, Merkel and Macron, pushing to align with China, since their ideals are much the same. The rotating presidency falls with Berlin this year.
Marxists have no morals, so it will depend on the rest of the EU to keep those two mongrels in line.
All-in-all, I think the world must confront China, Russia and Iran but I believe it could cost us all dearly. As it will absolutely take war and maybe several to do so effectively.
In a real world.
