"The Chinese entry into the war completed the process started in June. Again, American leaders did not see the degree to which their drive to the Yalu threatened Chinese security because they thought China knew that the United States was not a menace. As Acheson put it: "no possible shred of evidence could have existed in the minds of the Chinese Communists about the non-threatening intentions of the forces of the United Nations" (quoted in Spanier, 1965: 97). Since the Chinese counterattack then could not be seen as self-defense, the explanation had to be unprovoked Chinese hostility. Furthermore, for Dean Rusk, John Davies, and Edmund Clubb, the Chinese intervention served only Soviet interests and so showed that that country was controlled by Russia (FRUS, 1950, VII: 1080, 1088). Even if the Soviet Union had not ordered China to fight, the two countries clearly had parallel objectives and so would work together in the future. They were a bloc, and accretions of power to one of them aided the other. This is not to argue that the United States would have had good relations with China had there been no Korean war. As we discussed above, by early 1950 the U.S. government saw China as a menace and was stiffening its position. Many wanted to prevent the fall of Formosa, and almost all sought to prevent Communist expansion in Southeast Asia. The administration was on the defensive, with the bulk of mobilized opinion against it, blaming it for the "loss of China" and wanting to take a stronger position against the new regime. Further more, Acheson's expectations of Sino-Soviet friction were premature."
