That's an interesting analysis.

"Another possibility is that the US sells Taiwan out, something the US has shown it's very willing to do around the world. If the price is right, the US will turn a blind eye and let China put up a naval blockade, and from there it's a done deal."

This is a crucial point. On one hand you've got a guy who's ramping up the anti-Chinese rhetoric but nobody knows if it's just a bargaining tactic in which Taiwan would be sold down the river for a trade deal. On the other hand you've got Biden who seems like a China appeaser.

Taiwan highlights the fact that 'progressive' politics is crying out for someone who's not afraid to tell the truth - not some neo-liberal message-managed version of it - that translates as support for a totalitarian regime over a democratic one.
