The dropping of the Atomic Bomb on Hiroshima, Japan, in 1945 was one of the most controversial decisions of the 20th century.

Kamikazes were suicidal pilots who would crash their planes, which were packed with explosives, into American naval vessels. The Japanese were not a people accustomed to surrendering, and through their actions, they created the need to drop the Atomic Bomb.
