No country is perfect, especially the United States. How many war crimes have been committed in the last 50 years? China is not the enemy. We could learn a lot of positive things from them.
And it is a bloody dictature.

Given they have the biggest army in the world, this is the best way to have the most violent resolution of this antagonism.
