CHAINA!! threatening Taiwan is just a yearly tradition similar to Pride Month (soon to become Shame Month) in the west; lots of virtue signalling, the entire world responds with either support or opposition, and no actual action.
So every time I hear that Xi is threatening to invade Taiwan, I'm just like "yea, I know I know, it's that time of the year again...".

And I don't think the world has to fear CHAINA!!, it's a country that can't even manage to win wars within their own borders, and a country that has historically had a very hard time keeping itself together, plus it's a civilization of merchants, not warriors.
