China knows very well that using a nuke on U.S. would be 'game over' for them.

I suspect it will take a unified effort to end chinese imperialistic designs. Something along the lines of all of china's neighbors sinking all the chinese fishing boats anywhere near their waters all at the same time. And then promising china war with ALL of them if they don't mend their ways.

In my opinion, they need the backing of the United States.
This bears repeating: BIDEN IS WEAK.
