China's military capability is growing and we need to be on watch for that.
I seriously can't tell if you're trolling or not, and I'm sorry if you're not but in order for China to even be a minor threat to us they would need to be able to project force beyond their borders, and that requires aircraft carriers, supply ships, and global logistical support. Since their only aircraft carrier is non-operational militarily, and video of their newest fighter jet was stolen from Top Gun, there is nothing to be concerned about. Maybe if I was Taiwan I would be worried, but China is no where near capable of being a threat to the US. Purely militarily speaking of course.
Beyond that, our economies are interdependent. China and the US will not go to war in the foreseeable future for both military and economic reasons.
Besides, the McDonalds principle will prevail: no two nations that have McDonalds have gone to war with each other since the McDonalds was built.
