On August 6 and August 9 of 1945, warfare changed forever when the United States dropped two atomic bombs on Japan, devastating the cities of Hiroshima and Nagasaki and killing more than 100,000 people.
The attack on the people of Hiroshima at 8:15 a.m. on August 6, 1945, and the second attack on the city of Nagasaki at 11:02 am on August 9 killed and wounded hundreds of thousands of unsuspecting men, women, and children in a horrible blast of fire and radiation, followed by deadly fallout.
In years that followed, those who survived -- the hibakusha -- suffered from the trauma of the experience and from the long-term effects of their exposure to radiation from the weapons.
Before the blast, they were thriving cities. In a flash, they became desolate wastelands.
Seventy-five years later, take a glimpse at the destruction.
