一直以来，美国都向国民政府提供源源不断的援助，解放战争打响后，国民政府政权的腐败无能逐渐显露，呈现出垮台的局势。另一边，共产党逐步反击，共产主义不断发展壮大。面对这样的局面，美国当局对是否继续给予蒋介石政府以援助产生了疑虑，于是选派魏德迈组建调查团到中国进行实情调查，魏德迈调查团行走中国收集资料，整理出《魏德迈调查报告》希望美国政府继续支援蒋介石政府。为遏制共产主义的发展，魏德迈更是力陈满洲问题的严峻性，希望美国政府出面抵制共产党和苏联在中国继续扩张。然而，《魏德迈调查报告》最终却被马歇尔列为机密搁置一旁，美国对蒋的援助也迟迟落不到实处，时断时续的援助似乎是国民党的“吊命药”，更成了“催命符”。美国政府派出调查团的真实意图是什么，魏德迈调查团的调查活动是否曾对美国对蒋政策产生了影响，这就需要回归错综复杂的历史事件中，尽可能还原最接近真相的“真实”。

For a long time, the United States had been providing a steady stream of aid to the national government. After the war of liberation, the corruption and incompetence of the national government gradually revealed, and the regime presented a situation of collapse. On the other hand, the Communist Party gradually fought back, and communism continued to grow stronger and stronger. In the face of such a situation, the U.S. authorities had doubts about whether to continue to provide assistance to the Chiang Kai-shek government. Therefore, the U.S. authorities selected Wedemeyer to set up an investigation team to investigate the situation in China. The Wedemeyer investigation team traveled to China to collect data and compiled the Wedemeyer investigation report, which hoped that the U.S. government could continue to support the Chiang Kai-shek government. In order to curb the development of communism, Wedemeyer stressed the seriousness of the Manchuria issue and hoped that the U.S. government would boycott the continued expansion of the Communist Party and the Soviet Union in China. However, the Wedemeyer investigation report was finally classified as a top secret by Marshall. Meanwhile, the US aid to Chiang was slow to materialize. The intermittent assistance seemed to be the KMT's "hanging medicine", but also became a "reminder". What is the real intention of the US government to send an investigation mission? Had the investigation activities of the Wedemeyer investigation mission ever had an impact on the US policy towards Chiang Kai-Shek? This requires us to return to the intricate historical events and restore the "truth" as close to the truth as possible.
