@@-handweaving5081 1. RoC still exists today, PRC never finished their job of killing RoC. 2. RoC didn't control Taiwan either. In case you didn't know, Taiwan(and Korea) was under Japanese rule when RoC ruled Mainland China, well before WW2 started. Last time Taiwan was ruled by the Chinese was during Qing Dynasty, but Qing Dynasty was when China was ruled by the Manchus, not the Chinese Han. So technically it wasn't the Chinese, but Manchus who owned Taiwan before the Japanese. RoC took the islands when Japan itself was occupied by western powers after they lost WW2, and PRC never did anything about it physically. So Taiwan belongs to who now? Very complicated.
