On August 6, 1945, the United States becomes the first and only
nation to use atomic weaponry during wartime when it dropped an
atomic bomb on the Japanese city of Hiroshima. Approximately
80,000 people were killed as a direct result of the blast, while
another 35,000 were injured. At least another 60,000 would be
dead by the end of the year from the effects of the fallout.

Though the dropping of the atomic bomb on Japan marked the end
of World War II, many historians argue that it also ignited the Cold
War.
