Sixty-seven years after the US atomic bombs were dropped on Hiroshima and Nagasaki, about 20,000 nuclear weapons are still threatening the very survival of the human race. This threat must be rooted out as soon as possible. We call on people around the world to work together to achieve a world without nuclear weapons. The accident of the Fukushima Daiichi Nuclear Power Plant on March 11, 2011 has brought the horror of the nuclear dangers into sharper relief. We extend our solidarity with all nuclear victims.
