Nope, Mao wasn't mad, if he was mad, then no way that he could re-unite China into one.
Of course, in the eyes of the Soviets, Mao was a madman because he refused to let China to become a vassal state of USSR.
Only KMT was mad for starving 200 million of its own people. This party was nationalistic in the name only, since they were born traitors.
No need for apologist, since our Yankee friends didn't deny this fact either.
CPC developed the nukes to defend China, while KMT requested others to destroy China's nukes.
Let me telling you the truth, now the Mainland Chinese are getting more and more hostile towards Taiwan, and they hate KMT even more than DPP.
China is now starting to beat the war drum against its enemies.
