Remember the 70th anniversary of the Hiroshima bombing by watching this video of the weapon’s creator

Today (August 6) marks 70 years since the United States dropped an atomic bomb on the Japanese city of Hiroshima.

Three days later, on August 9, 1945, a second nuclear weapon was deployed against Nagasaki.

Together, the two bombs killed an estimated 140,000 civilians. They remain the only instances a nuclear weapon was ever used to target populated areas.

One month earlier, on July 16, 1945, the very first detonation of a nuclear weapon took place in a desert in New Mexico, in the United States. One of the bomb’s creators, J. Robert Oppenheimer, witnessed the event and said these words.

“We knew the world would not be the same. A few people laughed, a few people cried, most people were silent.

“I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the prince that he should do his duty, and to impress him takes on multiple form and says, ‘Now I am become Death, the destroyer of worlds.’

“I suppose we all thought that, one way or another.”
