You clearly have zero idea of the history of the Taiwan situation. The Island of Taiwan is and has been a part of the country of China for over a century. During the Chinese civil war, the losing army fled the mainland and retreated over the water to the island. The US and UK intervened with war ships and blockaded the island to protect the loser of the civil war. Why? Because the US and UK were already building relationships with the KMT to maintain their neocolonial holdings over China and they wanted the communists to lose so they could continue exploiting the people of China.

So now we have an island in China occupied by Chinese people and Chinese military but defended by Europe and what happens? Well, the KMT goes full fascist and executes the brutal and bloody White Terror for the next several decades while the US and UK protect them from their own countrymen, and feed them everything they need to develop their society on a foundation of brutal fascism and political repression.

What do you think happens when an entire population of people are isolated from their own society by abusers and develop under conditions when you get murdered by the state for even talking about the fact that you're all one China? You get the current political situation.

Taiwan as we know it is not and has never been a separate country from China. It has been a neocolonial project to isolate and abuse a portion of China by force to benefit the abuser and not the abused.

Nothing would be better for the people living on the island of Taiwan than for the Western empire to collapse and for slow integration with the rest of their country to begin. Everything would improve - economics, physical health, mental health, culture, crime, democracy, education, environmentalism, production, quality of life, etc.
