Memorandum by the Joint Chiefs of Staff to the Secretary of Defense (Wilson)

top secret

Subject:

  • United States Tactics Immediately Following an Armistice in Korea (NSC 154).
1.
In response to the request contained in your memorandum dated June 16, 1953, subject as above, the Joint Chiefs of Staff submit herewith their views on the draft statement of policy by the National Security Council Planning Board entitled “United States Tactics Immediately Following an Armistice in Korea” (NSC 154).
2.
The Joint Chiefs of Staff note that NSC 154 does not reflect the position taken in instructions issued to General Clark and Ambassador Briggs on May 30, 19533 with approval of the President to the effect that the United States is willing to enter into a mutual defense treaty with the ROK Government subject to receiving assurances from President Rhee that his Government will refrain from opposition to an armistice, cooperate in its implementation, and maintain forces under the control of the Commander in Chief, United Nations Command (CINCUNC). This position was restated in a letter of June 6, 1953 to President Rhee4 in which President Eisenhower stated that he was prepared after the conclusion and acceptance of an armistice to negotiate a [Page 1190] mutual defense treaty. The Joint Chiefs of Staff are of the opinion that in the absence of satisfactory assurances by the ROK Government that it will cooperate with the United Nations Command in carrying out the terms of an armistice, an offer to conclude a mutual defense treaty with that Government would result in a commitment on the part of the United States without any advantage in return. The Joint Chiefs of Staff, therefore, believe that paragraph 14 of NSC 154 should reaffirm the position adopted by the President in his letter of June 6, 1953 to President Rhee to the effect that acceptance by the ROK Government of an armistice agreement and cooperation in the implementation of its terms is a condition precedent to conclusion of a mutual defense treaty.
3.
The Joint Chiefs of Staff note that one of the Interim Courses of Action proposed in NSC 154 is that the United States conclude a treaty with the Republic of Korea (ROK) “guaranteeing its political independence and territorial integrity.” It is proposed that such a treaty cover the territory now or hereafter brought peacefully under the administration of the ROK. The Joint Chiefs of Staff are of the opinion that the language in which this course of action is couched is undesirably broad and could be interpreted to provide for numerous and unpredictable contingencies. It might well constitute an over-commitment of United States military forces and, in any event, would enlarge appreciably the current gap between the forces being maintained and their ability to meet United States commitments. Moreover, by implication, this course of action involves no requirement for a defense effort on the part of the ROK.
4.
In his letter to Mr. Rhee of June 6, 1953, President Eisenhower offered to negotiate with the ROK “a mutual-defense treaty along the lines of the treaties heretofore made between the United States and the Republic of the Philippines, and the United States and Australia and New Zealand.” In effect, these two treaties bind the Parties to consult together whenever in the opinion of any of them the territorial integrity, political independence, or security of any of the Parties is threatened. Further, each Party recognizes that an armed attack on any of the Parties would be dangerous to its own peace and safety and declares that it would act to meet the common danger in accordance with its constitutional processes. The Joint Chiefs of Staff, from the military point of view, regard a mutual-defense treaty of this nature as preferable to one which guarantees the political independence and territorial integrity of the ROK. Accordingly, they recommend that subparagraph 14b of NSC 154 be modified to bring it into consonance with the President’s proposal to Mr. Rhee.
5.
Subject to the foregoing proposed modification, the Joint Chiefs of Staff recommend that you concur in the draft statement of policy contained in NSC 154.
