“Now, over the last few decades, as the various global crises have been accumulating — climate change, the threat of nuclear war as well as the dangers of nuclear energy, the uncontrollability of the global financial system, and so on — we now hear people saying things like: “Look at what humanity has done.” Now suddenly the subject is “humanity,” whereas originally, Euro-Americans had claimed: “Look at the stunning achievements of the West.””

"Reaching Global Zero" (8 March 2011) http://www.huffingtonpost.com/valerie-plame-wilson/nuclear-proliferation_b_832399.html
Context: Without doubt, terrorist groups are trying to buy, build or steal a bomb. Furthermore, there is enough highly-enriched uranium (HEU) in the world to build more than 100,000 weapons, and rogue individuals are selling technology on the black market. If terrorists get hold of HEU, they could not be prevented from smuggling it into a targeted city, building a bomb and exploding it.
To my mind, the only realistic solution to this danger is to lock down all nuclear materials and eliminate all nuclear weapons in all countries: Global Zero. I am now dedicated to achieving this goal as a leader of the Global Zero movement. This movement was launched in December 2008 in Paris by an international group of 100 current and former heads-of-state, national security officials, military commanders and business, civic and faith leaders — and in just two years has grown to 300 leaders and 400,000 citizens worldwide.
The group believes that whatever deterrent value nuclear weapons had in the Cold War is now outweighed by the dangers of proliferation and nuclear terrorism. Our international Global Zero Commission has developed a practical, step-by-step plan to eliminate all nuclear weapons through phased and verified reductions.
To build on the progress made to date, we need a worldwide public movement to make Global Zero an urgent global imperative — and to bring all nuclear weapons countries to the table to negotiate multilateral nuclear arms reductions for the first time in history.

A Prescription for Hope (1985)
Context: Throughout human history, when confronted with what was deemed a deadly enemy, the fixed human response has been to gather more rocks, muskets, cannons, and now nuclear bombs. While nuclear weapons have no military utility — indeed they are not weapons but instruments of genocide-this essential truth is obscured by the notion of an "evil enemy". The "myth of the other", the stereotyping and demonizing of human beings beyond recognition, is still pervasive and now exacts inordinate economic, psychologic, and moral costs. The British physicist P. M. S. Blackett anticipated this state of paranoia: "Once a nation bases its security on an absolute weapon, such as the atom bomb, it becomes psychologically necessary to believe in an absolute enemy". The imagined enemy is eventually banished from the human family and reduced to an inanimate object whose annihilation loses all moral dimension.
