On the ones you mentioned:
Belarus and Burkina Faso maybe. Cyprus and Greece definitely not, they are too deeply embedded in the West's system. And Haiti and Swaziland are very unlikely, seeing as there is already looming imperialist intervention in Haiti and i don't know much about Swaziland but the monarchy seems pretty stable there.
Taiwan reunification is an inevitability. It's not a question of if it's just when.
