Interesting calculation on China’s part. When push comes to shove is the West willing to invest blood and treasure to stop China from invading Taiwan. My guess is no
With respect to broader military action, I would suggest that Military’s that prioritize senior leadership political purity over military competence, which is a feature of all dictatorships, don’t do well when they come up against a modern Western military.
China’s military might look pretty on the parade square, but when the fights on I think they will prove a lot less capable then they look.
