NSC-68 (National Security Council Report 68) was a classified United States government policy document submitted to President Harry Truman on April 14, 1950, which argued that the Soviet Union's military buildup - accelerated by its August 1949 atomic bomb test - required the United States to dramatically increase defense spending and adopt a comprehensively militarized approach to Cold War competition. Written by Paul Nitze, who had replaced George Kennan as director of the State Department's Policy Planning Staff, NSC-68 effectively superseded Kennan's original containment concept with a military interpretation Kennan explicitly opposed. Truman formally approved NSC-68 on September 30, 1950, after the outbreak of the Korean War had appeared to confirm its threat assessment.¹

Origins and Authorship

NSC-68 was produced in response to the twin shocks of 1949: the Soviet atomic bomb test in August and the communist victory in China in October. President Truman directed the National Security Council to produce a comprehensive review of American national security policy. Nitze, who had succeeded Kennan as Policy Planning director in January 1950, led the drafting process, working with representatives from the Department of Defense and other agencies.

Kennan, who was still in the State Department as a counselor, was deliberately excluded from the drafting process. His alternative framework - which emphasized that Soviet policy was primarily politically driven and that the Soviet threat could be met through economic, political, and psychological means rather than military buildup - was rejected as the analytical foundation for the review.¹

Arguments and Recommendations

NSC-68 characterized the Soviet Union as implacably hostile to the American system and argued that Soviet military capabilities, rather than Soviet political intentions, should drive American planning. The document assessed that the Soviet Union would reach the capability to deliver a decisive atomic blow against the United States by approximately 1954 - "the year of maximum danger."

The document recommended that the United States increase defense spending from approximately $14 billion annually to somewhere between $35 and $50 billion - roughly tripling or quadrupling the defense budget. This recommendation was presented as the minimum necessary to maintain military forces capable of deterring Soviet aggression across a range of contingencies.

NSC-68 also argued for developing the hydrogen bomb, building conventional military forces sufficient to fight a major war, and mobilizing American public and private institutions for sustained competition with the Soviet Union.¹

Korean War and Implementation

NSC-68 had been submitted to Truman but not yet approved when North Korea invaded South Korea on June 25, 1950. The Korean War appeared to validate NSC-68's argument that the Soviet threat was military and immediate. Truman approved NSC-68 in September 1950 and the defense spending increases it called for were implemented: American defense spending rose from approximately $13 billion in fiscal 1950 to $48 billion in fiscal 1952.

The document remained classified until 1975, when it was declassified in the aftermath of the Church Committee investigations into intelligence abuses. Its declassification allowed historians to document the specific policy debate between Kennan and Nitze over the nature of containment that had occurred at the founding of American Cold War strategy.²

Kennan's Opposition

Kennan regarded NSC-68 as a fundamental misreading of Soviet policy and American interests. He argued that the Soviet threat was political and that a massive military buildup would provoke a mirror-image Soviet response, produce a militarized Cold War neither side could win, and crowd out the economic and diplomatic tools that were actually effective against Soviet influence.

In his memoirs, Kennan identified NSC-68 as the document that transformed containment from a political concept he had designed into a military crusade he had not intended. The subsequent arc of the Cold War - including the nuclear arms race, the Korean and Vietnam Wars, and the enormous defense budgets of the 1950s and 1960s - he viewed as flowing from the choices NSC-68 institutionalized.¹
