在中国抗日战争前期,美国从自身利益出发,采取了保守的“中立”观望态度。1941年太平洋战争爆发后,美国对中国抗战事业给予支持与合作,让中国军队牵制日本陆军主力,减轻美国在太平洋战场上的压力。随着世界反法西斯战争的不断胜利,美国又实行“扶蒋反共”的对华政策,帮助蒋介石夺取人民抗战的胜利果实。在抗战时期,美国对华政策经历了中立、结盟到“扶蒋反共”的演变;其每一步都是从美国自身利益出发的。 In the early days of the Anti-Japanese War in China, the United States adopted a conservative “neutral” wait-and-see attitude based on its own interests. After the outbreak of the Pacific War in 1941, the United States gave its support and cooperation to the cause of China’s war of resistance against Japan, allowing the Chinese military to contain the main force of the Japanese army and ease the pressure on the U.S. battlefield in the Pacific. As the world victoriously defeated the anti-fascist war, the United States has also implemented its “policy of helping Chiang Kai-shek and the Anti-Communists” toward China and helped Chiang Kai-shek to win the victory of the people’s war of resistance. During the war of resistance against Japan, the U.S. policy on China went through a neutral process of alliance to the evolution of “helping Chiang Kai-shek and the Anti-Communists.” Each step of the U.S. embarks on its own self-interest.
