Allied victory had rescued humanity from a dark future, but for President Truman and his administration, the celebrations were short lived.

With Japan’s defeat, World War II finally came to an end. The formal end of World War II took place in suitably dramatic fashion, with a surrender ceremony on board the USS Missouri on September 2, 1945.

In the hours after Truman drops the bomb on Hiroshima, news reports begin to surface of “a city vanished.”

In July 1945, after the success of the Trinity Test, President Truman ordered that the new atomic bombs be ready for assembly and potential use as quickly as possible.

World War II had been so horrible that the victorious powers decided that nothing like it must ever happen again.  President Roosevelt’s dream had been to establish a “United Nations” (UN) organization, in which the peace-loving nations of the world would settle disputes and intervene to punish aggression, but it was Truman who saw it through.
