He was anticommunist so he wanted to stop it from spreading. He decided that under the 'Truman Doctrine' the US would help any nation that was in danger of falling to communism. This was his policy of containment, his foreign policy.

It was the Truman Administration that adopted the policy of containment, which was designed to block the spread of Communism throughout the world. The policy was followed by every subsequent administration until the Cold War ended in 1989.
I don't think he did. The US policy was one of containment of communism which led us into Southeast Asia and the Cold War for 60 years. This became the official policy for presidents from Truman to Clinton. JFK tried to change the mindset and he may have successfully completed it if he had served his second term in office.

President Harry Truman isssued the policy of containment
The Cold War began in 1947 and lasted until 1991. Harry S. Truman, America's 33rd President, served from 1945 to 1953. Truman was followed by Dwight D. Eisenhower from 1953-1961, and John F. Kennedy from 1961-1963. The next few presidents were Lyndon B. Johnson, Richard Nixon, and Gerald Ford.
President Harry S. Truman created the Truman Doctrine which called for the policy of containment during the Cold War era.
Truman actually gave the command to detonate the first nuclear weapon & he was the US president in office when man left the old world (conventional) and crossed into the atomic age in 1945. When that A-Bomb went off, the cold war began...even though the Soviets didn't get their bomb until 1949 (stolen from the US via spies).
