[Mr Rogers]

Chiang’s men were bad. The communists were worse. And Chiang DID have the ability to beat the Communists, except communist sympathizers in our government withheld aid...because Mao ‘cared more’ about the poor.

[Eric in the Ozarks]

To understand how awful Chiang was in regard to his fellow Chinese on mainland China, consider the fate of the native Taiwanese after Chiang & his army arrived on the island in 1949. Taiwanese from that era say you could flip a coin as to who was worse, Chiang or the Imperial Japanese Army.
The Nationalists had given up the fight against Japan early on in the war and history records the officer corps' focus was almost completely on what they could steal, dismantle and carry off for their own account. Virtually every reference on the China-Burma-India Campaign makes mention of this. My dad was a Hump pilot and never had a good word to say about Chiang or his wife the Dragon Lady (if anyone remembers who financed her it was the United states congress.) Pointlessly, American money flushed through the Chiang family and made them royalty in Formosa. Very limited benefit came to the US as a result.
