It is important to remember that the damage done in 1945 is based on a bomb size of 10-20 kilotons. A single nuclear warhead today could easily be 50-100 times more powerful (1 megaton).
Over 26 000 nuclear warheads remain today, the majority held by the USA and Russia, with China, France, the United Kingdom, India, Pakistan, Israel and possibly North Korea possessing the rest.
A modern nuclear war, even if limited to a single region such as South Asia, could cause between 5 million and 30 million deaths and have devastating effects on our planet, leading to critical cooling of the global climate for over a decade and ozone depletion.
As world resources become scarce, potential for conflict over water, food and fuel will increase, as will the threat of use of nuclear weapons.
Through examining the devastation of the atomic bombs, it becomes clear that living under the threat of nuclear weapons is no longer an option.
