McCarran Act – In 1950 Truman vetoed the McCarran Internal Security Bill, which among other provisions authorized the president to arrest and detain suspicious people during an “internal security emergency.” Even so, Congress enacted the bill over Truman’s veto.
Dixiecrats – J. Strom Thurmond was nominated for president for the States' Rights Party (“Dixiecrats”) in the 1948 election. This party split Southern Democrats from the party along racial lines. He only got 39 electoral votes.
Fail Deal – For domestic policy, Truman outlined a Fair Deal policy in his 1949 message to Congress. It called for improved housing, full employment, a higher minimum wage, better farm price supports, new TVAs, and an extension of Social Security. However, much of the Fair Deal policies were crushed by the Republican Congress, with the only major successes coming from a rise in the minimum wage, the passing of the Housing Act of 1949 providing for public housing, and extending old-age insurance to many more beneficiaries in the Social Security Act of 1950.
NSC-68 – On June 25, 1950, North Korean forces poured across the 28th parallel into South Korean land, pushing the South Korean’s back southward to a tiny defensive area around Pusan. Truman jumped into action, seeing the invasion as devastating proof of the “containment doctrine.” The Korean invasion provided the occasion for a vast expansion of the American military – the National Security Council had recommended in a famous document of 1950 (NSC-68) that the US should quadruple its defense spending, and the Korean War provided an occasion to implement this plan. Soon the US had 3.5 million men under arms and was spending $50 billion per year on the defense budget (13% of the GNP). NSC-68 was a key document of the Cold War, because it marked a major step in the militarization of American foreign policy and was based on the assumption that the enormous American economy could bear without strain the huge costs of a gigantic rearmament program.
