Is it plausible for the US Armed Forces to become involved in the Chinese Civil War, obviously on the side of the KMT, in a significant way?
Wikipedia said:The Nanjing incident, or Nanking incident occurred in March 1927 during the capture of the city by Communist forces from the Nationalists.
A Communist army was marching south to take the city which was a center of foreign trading activity as well as the capital of Nationalist China. When the Communists neared the city, the overwhelmed Nationalist officers deserted so riots broke out as the enlisted men began to retreat but about 10,000 were trapped within the city without transportation to leave while over 70,000 Communists prepared to enter.
Nationalists who were supposed to defend the city began burning houses and attacked the British, American and Japanese consulates, killing the British and Japanese consuls in the process. Uniformed Communists executed the American vice president of Nanking University, Doctor John Elias Williams. Soldiers of the 6th Army systematically looted the homes and businesses of the foreign residents. One Japanese naval officer was killed along with at least one Frenchmen and one Italian.
The Chinese forces stormed the consulates of America, Britain, and Japan, looting nearly every foreign property and almost assassinating the Japanese consul. An American, two British, one French, an Italian, and a Japanese were killed by Chinese Nationalist forces. Chinese snipers targeted the American consul and marines who were guarding him, Chinese bullets forced them to flee into Sacony Hall where American citizens were hiding out, one Chinese soldier declared, "We don't want money, anyway, we want to kill."
