Honest question, from non-american: what is up with all the China scare? I just can't understand it. Is it because China is socialist and we want to see capitalism winning over?

It's easier to explain if we knew your country. But in general: limited resources, us vs them, etc. Same thing as Rome vs Carthage.

It's because Xi has demanded that China's military be ready to invade and conquer Taiwan by 2027. It's because Xi has made reunification with Taiwan a test of the legitimacy of the CCP's rule over China. The combination of those two things gives you a "China scare" with respect to Taiwan, out of Xi's own mouth.

I think the west is scared of China trying to take over the world by force like the USSR.
