You guys don't even know shit about Chinese history, Taiwan was always China's but it got conqued by japan in the 1890s the Japanese gave back Taiwan when they lost ww2, then civil wars broke up in China the communist party drove the Kuomintang party to Taiwan, The ruling party in taiwan(Kuomintang party)still reconize themselfs as Chinese but not a part of The Peoples Republic Of China!
As for Tibet, Tibet was a part of China since the 13 century, the Dala Lama wants to split Tibet even though the people don't, if there was a vote there then the Dala Lama would not win, the Dala Lama is just an idoit who escape to India when the civil war ended, now with dreams to split China, which is not going to happen!

"I don't know what the facts are but somebody's certainly going to sit down with him and find out what he knows that they may not know, and make sure he knows what they know that he may not know."
