The Security Council held two meetings (1140th and 1141st) on August 5 and 7, 1964, to discuss a complaint of the United States government against the government of North Vietnam, which was expressed in a letter dated August 4, 1964, from the permanent representative of the United States addressed to the President of the Security Council. At the outset of the 1140th meeting on August 5, 1964, Mr. Morozov (Soviet Union) explained that he had requested the postponement of the meeting until August 6 to permit his delegation to receive necessary instructions from its government. With regard to this request, Mr. Stevenson (United States) pointed out that the UN Charter explicitly called for immediate reporting to the Council of measures taken by Members in the exercise of their right of self-defense. If the Council wished to adjourn after hearing the statement of the United States delegation, Mr. Stevenson had no objection. Mr. Hajek (Czechoslovakia) also opposed convening the meeting on August 5 on the grounds that Council members did not possess all the facts and views of the parties. To deliberate on the question on the basis of one version would not, he felt, serve the interests of the Council. Moreover, he did not feel that the circumstances constituted an emergency: The United States did not appear to be immediately threatened.
