I hope Taiwan will not be invaded militarily. However, Taiwanese no longer has any agency on this. There are two scenarios where I think Taiwan can re-unite with China in a non-military way.
1. The U.S., in a deep crisis, decided to trade Taiwan back to China for some immediate relief.
If I were the president of the United States, it would be hard for me to give up this perfect "customer".Americans can blackmail Taiwan Island and Chinese Mainland at the same time.Taiwanese provide a lot of funds to American political lobbying groups every year, too many people have reasons not to give up.
2. The Chinese military power has grown to such a point that Taiwan is no longer needed for the Chinese to assert their regional dominance. If this couple with the Chinese gained access to ports in the Philippines, Indonesia etc., we may reach a point where the U.S. decides to leave East Asia. In that case, Japan, along with Taiwan, will have no choice but to return to the fold of China.
On this point, things are not that simple.As I said earlier, the Taiwan regime can do things that Americans cannot do in intelligence collection,because the cultural atmosphere is highly similar and there is no language barrier, Taiwanese people can better complete intelligence collection, bribery and public opinion incitement than ABC.
China's nuclear submarines have been closely monitored during navigation, and many intelligence has been provided to the United States and Japan by Taiwanese.
Considering Tsai ing Wen's involvement in the Hong Kong riots, Taiwan is undoubtedly the biggest hidden danger to China's national security,some naive dissidents in China try to use this former regime as their spiritual totem.
Before the covid-19 crisis broke out, some people believed that the United States would take the initiative to provoke conflicts by taking advantage of the current advantages of Navy, air force and tactical nuclear weapons(assuming that China dare not escalate into a full-scale nuclear war because of the small number of nuclear weapons) in order to save the decline.
At that time, the situation in the Taiwan Strait was deteriorating,Taiwan independence elements urgently hope that Trump will launch a "war of punishment" against China.
Trump gave the impression of being aggressive at that time, and the attack on Soleimani made people believe that he did things recklessly.No one would have thought that the Capitol Hill incident and the "Bunker boy" incident exposed his timid true face.
Up to now, you can see that the intervention plans for Taiwan discussed by all sectors of the United States are very radical,launching a surprise attack on China's landing fleet has always been an option discussed,even if it means a large-scale war.
So——
This would locked the U.S. into an arms race against a country that may have 2x the gdp as the U.S. someday and an industrial sector that is multiple times the size of the U.S.
I don't see the possibility of America stopping.They are too obsessed with "absolute advantage".Their dominant position in the past has made them lose the possibility of compromise and concession, unless they encounter a humiliating failure like Afghanistan.
