At the time it was fought, the war in Korea was unique in recent American military experience. Unlike World Wars I and II, which were vigorously prosecuted on the battlefield until the enemy surrendered unconditionally, the Korean conflict ended without clear-cut military victory for either side. It was fought with limited means for limited objectives. In fact, political efforts to resolve the conflict at the negotiating table predominated during the last two years of the conflict. During this period, neither side sought a decision by military means. The conflict in Korea also was an important milestone in the "cold war" relations between the Communist and non-Communist nations. By launching an unprovoked attack on a militarily insignificant country located in an area where none of their vital interests were involved, the Communists appeared to leaders of the non-Communist states to be giving proof of their aggressive designs for world domination. As a result, the United States reversed the policy of reducing its military establishment and launched an impressive expansion of its armed forces. At the same time, the United States joined with its North Atlantic Treaty Organization (NATO) partners to create a military command for the alliance and to incorporate German forces in it. In the Far East, the United States also acted to shore up the defenses of the non-Communist world by entering into treaties with Australia and New Zealand, the Philippines, Japan, South Korea, and Nationalist China. The Korean War provided the first wartime test for the Joint Chiefs of Staff, acting as part of the machinery set up by the National Security Act of 1947 and its 1949 amendment. In this capacity, they provided strategic direction to the United Nations (UN) forces in the field and were the agency by which President Truman exercised overall control of war strategy. When the focus shifted from combat to armistice negotiations, the JCS continued to play an active role. They participated in all the key decisions taken during negotiations, and they provided the channel of communications between the government in Washington and Commander in Chief, United Nations Command (CINCUNC), and his armistice negotiating team in Korea. The focus of this volume is, naturally, on the Joint Chiefs of Staff. But as they were not acting in a vacuum, it has been necessary to describe the context in which they functioned. To this end, the actions of the President and the Secretaries of State and Defense concerning overall military strategy and armistice negotiations have been described in some detail. In addition, the consequences of these actions, on the battlefield and at the negotiating table, have been sketched in broad outline.
