Diplomatically, President Truman's decision to use the atomic bomb in Japan may have been partially motivated by his desire to limit the involvement of the Soviet Union in the Pacific War.
President Harry Truman, was the 33rd President of the United States of America, who was in office during World War II, when he decided to use atomic bombs on the Japanese cities of Hiroshima and Nagasaki.
The main motivation for the attack was to get back on Japan after the Pearl Harbor attack, but some may argue that it was also a demonstration of power to drive other nations away from combat with the United States.
The Space Race was considered important because it showed the world which country had the best science, technology, and economic system. After World War II both the United States and the Soviet Union realized how important rocket research would be to the military.
