What is your opinion regarding Chiang?
When I first started investigating about modern Chinese history, I regarded him like a tragic figure. A patriot that did his best to modernize China, and fight Japan only to be expelled to Taiwan never to return to the mainland.
Latter I learn about the shanghai massacre (which alienate the Soviet union which was helping to modernize China, launch the disastrous civil war)
His refusal to defend Manchuria even when the invasion was unpopular in Japan at the time. His appeasement of Japan was so big that he had to be literally kidnapped to agree to fight Japan.
So what you think would China have been better with any other leader?
