Since the Korean War, United States policies in Asia have gradually developed along the lines of the “containment” doctrine so successfully applied in Europe after 1947. Washington has increasingly seen the problem of Chinese power in Asia in much the same light as that posed by Soviet power in Europe and has behaved as if both threats could be contained by basically the same kinds of responses. In both Asia and Europe, containment measures have reflected a perceived need for complementary interaction between military policies and aid programs in order to prevent aggression by Communist powers and to foster the internal stability of nations in the area. Although difficulties have arisen in seeking the best balance of these components of the containment policy in Europe, most of the essential American objectives in the West have been attained.
