When our ships sail near their lands it "freedom of navigation", when their's do it near us it's "provocative" ["proactive"]...
Do you bite your thumb at us ? / I do bite my thumb / Do you bite your thumb at us sir ?

Sure, they bluster. But that would be really stupid. "You said something I don't like, so I'm going to kill us both" level of stupid. China talks tough, but I don't think they're actually that stupid.
The US walks a line on Taiwan that falls far short of actual support for One China but does enough to support it that the US has a lot of room to escalate with China if the US wants to without starting WW3.
It's a real cluster fuck.
