@detectivemittens I may sound like a broken plate but I think it’s precisely the situation in Ukraine that is giving them hopes. Had the US not put on hold that package for Ukraine, the Chinese could have simply taken a more moderate stance towards Taiwan. By doing what it did, yea, as you said, the US showed its weakness in providing its allies and partners with the required military help.
The arrangement with Taiwan is different though. A war between the two Chinas would see direct US involvement, not just the sending over of old weapons that are well past their expiration date.
