Taiwan and the US will keep salami-slicing through. While the core "independence" thing will still remain intact for China, Taiwan will become more a "country".
More internationally recognised, enter more trade agreements, cut off their Chinese connections, more high-profile diplomatic visits, more military sales etc.
So this salamy-slicing works. They will change their name, ban the PRC flag, and dropping their "China" claims. This is becoming clearer by the day, with US support.
This salami-slicing is not inconsequential, it poses dangers and losses for China if not countered
This person seems to be of the opposite opinion from your prognostications. I am not saying that I agree with all the points this fella is saying but more or less I agree with the main thrust of his arguments made on the video.
