"you think Taiwan could exist as an independent country"

It has done for nearly 80 years recently and for hundreds of years before. It was only under Chinese jurisdiction for a very short while. I suggest you avail yourself of some facts before going off on a silly tirade.

Taiwan has been settled for at least 25,000 years. Ancestors of Taiwanese indigenous peoples settled the island around 6,000 years ago. In the 17th century, large-scale Han Chinese immigration to western Taiwan began under a Dutch colony and continued under the Kingdom of Tungning. The island was annexed in 1683 by the Qing dynasty of China, and ceded to the Empire of Japan in 1895. The Republic of China, which had overthrown the Qing in 1911, took control of Taiwan on behalf of the Allies of World War II following the surrender of Japan in 1945. The resumption of the Chinese Civil War resulted in the ROC's loss of mainland China to forces of the Chinese Communist Party (CCP) and consequent retreat to Taiwan in 1949. Its effective jurisdiction has since been limited to Taiwan and smaller islands.
