I think the most important event of the 1940's was World War 2. On December 7, 1941 Japan bombed Pearl Harbor Hawaii which pushed America into the war. In August of 1945 President Truman ordered the 2 atomic bombs to be dropped on Japan in Hiroshima and Nagasaki. The bombs devastated Japan and forced them to end the war between the United States and Japan. After the war the "Marshall plan" was implemented for the rebuilding of Europe.
