In order to understand the policy of the United States towards China it is necessary to go back to die Chinese civil war. It is at this point that the confusion over ‘the real issue obscured the thinking and frustrated the policies of the United States. When it became obvious that the Nationalist régime was unable to cope with the revolutionary situation even if supported by American arms and advice, only two courses, which General Wedemeyer's report of 1947 clearly envisaged, were logically open to American policy. One was military intervention on such a scale as to be sufficient not only to crush the Communist armies but also to keep discontent permanently in check. Military intervention of this kind would have entailed military and political commitments of incalculable magnitude. This course of action was rejected by the framers of the United States' foreign policy on the advice, among others, of the then-Secretary of State, George Marshall.
