25. In view of the world-wide reaction to overt aggression in Korea, Communist China may prefer to repeat in Indochina the method of "volunteer" intervention. Inasmuch as the French do not control the border between China and Indochina nor large areas north of Hanoi, it may be difficult to detect the extent of preparation for such intervention. It is important to U.S. security interests to maintain the closest possible consultation with the French Government on the buildup of Chinese Communist intervention in Indochina. The Government of France has agreed to consult with the United States before it requests UN or other international action to oppose Chinese Communist aggression in Indochina in order that the two countries may jointly evaluate the extent of Chinese Communist intervention.
26. If it is thus determined that Chinese Communist forces (including volunteers) have overtly intervened in the conflict in Indochina, or are covertly participating to such an extent as to jeopardize retention of the Tonkin Delta by the French forces, the United States should support the French to the greatest extent possible, preferably under the auspices of the UN. It is by no means certain that an appropriate UN resolution could be obtained. Favorable action in the UN would depend upon a change in the attitude of those governments which view the present regime in Indochina as a continuation of French colonialism. A new communist aggression might bring about a reassessment of the situation on the part of these governments and an increased recognition of the danger. Accordingly, it is believed that a UK resolution to oppose the aggression could be passed in the General Assembly by a small margin.
27. Even if it is not possible to obtain a UN resolution in such a case, the United States should seek the maximum possible international support for and participation in any international collective action in support of France and the Associated States. The United States should take appropriate military action against Communist China as part of a UN collective action or in conjunction with France and the United Kingdom and other friendly governments. However, in the absence of such support, it is highly unlikely that the United States would, act unilaterally. It is probable however, that the United States would find some support and token participation at least from the United Kingdom and other Commonwealth countries.
