I doubt they think that. You’re being ridiculous. Taiwan is de facto independent, and there is some push over there to declare independence officially. The ROC is of a different era at the end of the day.
The USA doesn’t officially recognize the ROC but it is US law that consular, travel and business relations between them. Nancy Pelosi travelled to Tawain only a couple years ago.
Anyway, the rights for all people to self-govern themselves should come first over all that.
I am not a US citizen and there are plenty of instances of the US government not supporting self-determination. I was talking about myself and I would hope most people’s opinion worldwide, not some governement.
The PRC didn’t invade Tawia when they the ROC’s army fled there. Is that because of the USA? Taiwan has been seperate from China for almost eighty years now, that’s a long time!
