The US economy was booming like it never had by the end of World War II. The problem was that it was based on military spending, which was no longer needed at the same level. The trick was to transition from a war economy to a civilian economy. Intrinsically this was going to cause a decline in production. However, Truman saw how badly Europe was devastated by the war and used American resources to help rebuild. The US offered all sorts of supplies and goods to its allies and former enemies. The Truman Doctrine was passed to do specifically this. The US also helped to rebuild Japan.
