True, nobody has been killed by a nuclear weapon since the attacks on Hiroshima and Nagasaki, 65 years ago this month.

On August 6, 1945, in the final days of World War II, an American aircraft dropped an atomic bomb on the city of Hiroshima in western Japan.

The current stockpile of nuclear weapons represents more than a million times the explosive power of the bomb whose destruction of Hiroshima so grieved him.

For example, in 1995 the Smithsonian Institution in Washington sought to take a fresh look at the Enola Gay , the plane that dropped the atomic bomb on Hiroshima.

Nuclear armed nations built nearly 100,000 nuclear weapons, bearing the explosive power of about a million six hundred thousand Hiroshima size bombs. With the Cold War s end, arms reductions began, but the nuclear powers America in particular publicly disavowed total nuclear disarmament for the indefinite future, in the recent words of Robert Bell, of the US National Security Council.

Nuclear armed nations built nearly 100,000 nuclear weapons, bearing the explosive power of about a million six hundred thousand Hiroshima size bombs.

Yet there are still 23,000 nuclear warheads on our planet, with the explosive power of 150,000 Hiroshima bombs.

Indeed, the very existence of the Japanese nation was endangered, as most cities were bombed, Okinawa was invaded, and atomic bombs were dropped on Hiroshima and Nagasaki.

When they bombed Hiroshima, the explosion formed a mini supernova so every living animal, human or plant that received direct contact with the rays from that sun was instantly turned to ash.

Not even considering people who fought on the frontlines or experienced the destruction of war, there are very few Japanese alive today who have childhood memories of the conflict.

But it is not naïve to be concerned about the most indiscriminately inhumane weapons of destruction ever invented 23,000 of which still exist with a combined destructive capability of 150,000 Hiroshima bombs.

And that is, on August 6th, 1945, a B 29 bomber called the Enola Gay flew over Japan and, using a Norden bombsight, dropped a very large thermonuclear device on the city of Hiroshima.

Existing global stockpiles have a destructive capacity equal to 150,000 Hiroshima bombs, and in handling them there is an omnipresent potential for human error, system error, or misjudgment under stress.

Indonesia's Agency for the Assessment and Application of Technology (BPPT) said in statement the energy released by Friday's massive quake was around 200 times the power of the atomic bomb dropped on Hiroshima in World War Two.

Rapidly appropriating the lessons of nineteenth century Europe, Japan in 1894 launched a brutal five decade effort to dominate Asia and secure its resources, stopping only when America s atomic bombs flattened Hiroshima and Nagasaki.

This is more than twice the total explosive energy used during all of World War II (including the two atomic bombs) but still a couple of orders of magnitude less than the energy released in the earthquake itself.

More than 70 years since the atomic bombs fell upon Hiroshima and Nagasaki, said project lead Hidenori Watanave in an interview with Global Voices about the Hiroshima Archive. Few survivors remain today and soon there will be none.
