1. To prevent the countries of Southeast Asia from passing into the communist orbit, and to assist them to develop the will and ability to resist communism from within and without and to contribute to the strengthening of the free world.
2. Communist domination, by whatever means, of all Southeast Asia would seriously endanger in the short term, and critically endanger in the longer term, United States security interests.
a. The loss of any of the countries of Southeast Asia to communist control as a consequence of overt or covert Chinese Communist aggression would have critical psychological, political and economic consequences. In the absence of effective and timely counteraction, the loss of any single country would probably lead to relatively swift submission to or an alignment with communism by the remaining countries of this group. Furthermore, an alignment with communism of the rest of Southeast Asia and India, and in the longer term, of the Middle East (with the probable exceptions of at least Pakistan and Turkey) would in all probability progressively follow. Such widespread alignment would endanger the stability and security of Europe.
b. Communist control of all of Southeast Asia would render the U.S. position in the Pacific offshore island chain precarious and would seriously jeopardize fundamental U.S. security interests in the Far East.
c. Southeast Asia, especially Malaya and Indonesia, is the principal world source of natural rubber and tin, and a producer of petroleum and other strategically important commodities. The rice exports of Burma and Thailand are critically important to Malaya, Ceylon and Hong Kong and are of considerable significance to Japan and India, all important areas of free Asia.
d. The loss of Southeast Asia, especially of Malaya and Indonesia, could result in such economic and political pressures in Japan as to make it extremely difficult to prevent Japan's eventual accommodation to communism. . . .
4. The danger of an overt military attack against Southeast Asia is inherent in the existence of a hostile and aggressive Communist China, but such an attack is less probable than continued communist efforts to achieve domination through subversion. The primary threat to Southeast Asia accordingly arises from the possibility that the situation in Indochina may deteriorate as a result of the weakening of the resolve of, or as a result of the inability of the governments of France and of the Associated States to continue to oppose the Viet Minh rebellion, the military strength of which is being steadily increased by virtue of aid furnished by the Chinese Communist regime and its allies.
