What measures did the USA take in stoppingCommunism
The United States tried to stop the spread of Communism by repeatedly defending in wars where the country in concern was in danger of being overwhelmed by a Communist neighbour. For example, the United States defended South Korea against the Communist North Korea, and lost South Vietnam to the Communist North Vietnam. The United States also eagerly purged any Communists from their government. The policy of containment was applied and tested throughout Truman's administration and the Cold War as well. The money propped up both economies in the end, and eventually Communism did not spread. In 1945, the Act of Chapultepec that was signed by the ministers of most countries in the hemisphere called for collective measures in case of an attack on a signatory state by an extra continental power. The Rio Conference of countries of the hemisphere produces the Rio Treat (The Inter-American Treaty on Reciprocal Assistance). Under the treaty, states are committed to assist in meeting armed attacks although no state could be compelled to use force.
