Remember the 70th anniversary of the Hiroshima bombing by watching this video

Children, elderly survivors and delegates representing 100 countries were in the crowd with many placing flowers in front of the cenotaph at Peace Memorial Park, as doves were released into the air. Almost everything around it was incinerated by a wall of heat up to 4,000 degrees Celsius – hot enough to melt steel.

Japan marked the 70th anniversary of the atomic bombing of Hiroshima on Thursday, with Mayor Kazumi Matsui renewing calls for U.S. President Barack Obama and other world leaders to step up efforts toward making a nuclear-weapons-free world.

“The horror of these bombings should be taken as a warning of the threats of nuclear weapons, but instead, the government is locking Japan into a nuclear future”.

Japan plans to submit a fresh resolution to abolish nuclear weapons at the UN general assembly later this year, he said. A bill passed through the Lower House on July this year, and the Upper House has already begun discussions on legislation which could roll back some of the provisions in the constitution allowing the country to participate in the wars of allied nations.

Prime Minister Abe mourned the souls lost in Hiroshima earlier today, but in the days ahead, he faces a hard task, to acknowledge the lessons of history and reposition his country amid the enduring mistrust of his neighbors.

Witnessing the destruction, Robert Lewis, the co-pilot of the U.S. bomber Enola Gay later wrote, “My God what have we done?”

His experience as a survivor of the world’s first nuclear attack led him to spend much of the past 70 years reflecting “on how humans could make peace”, said Tsunoi, who just celebrated his 90th birthday.

Following the bombing, the cities of Hiroshima and Nagasaki became known for their high rates of cancers, premature births and malformed babies.

“I don’t know why I survived and lived this long”. Many others were killed in Nagasaki and in the days to follow.

Moscow residents also brought 1,000 origami cranes to the US embassy in central Moscow to commemorate the (at least) 200,000 victims of the atomic bombing of the Japanese cities of Hiroshima and Nagasaki, which occurred on 6 and 9 August 1945 respectively.

The US demonstrated unprecedented power when it dropped the atomic bombs.

“We are all growing older”, he said.

The attack by the United States, was intended to end the war in the Pacific.

But its militarist past evokes strong emotions, particularly in China and Korea, which suffered from Japan’s brutal march across Asia.

“People are against war all the time but they forget the Revolutionary War, they forget the Civil War, it made America”, he said.
