The HK situation provides most of the information we need to predict the future relationship between Taiwan and the PRC. Did anyone actually believe that the PRC would be prepared to tolerate a fundamentally contrary political system persisting inside China? It was always clear that the Chinese government would allow a "decent interval" to elapse before starting to assimilate HK completely - as we see happening now. The idea that the PRC will ever reconcile itself to the existence of a second "Chinese Government" in Taiwan is preposterous. This is a long game but there's only one likely outcome.
