The world will only support it if the Chinese reject communism. More likely is Taiwan is "persuaded" just as Hong Kong was to unify, while the Chinese remain communist. Which may finally wake some people up to the danger.
I can accept that. But until then, the pressure needs to be kept on Taiwan so that the two are eventually country. This is not just the desire on the part of the Chinese government, but also of the people. And yes, pressure needs to kept on China to become a democracy. I believe both will happen.
