Einstein long ago said, ‘With the splitting of the atom everything has changed except our modes of thinking and thus we drift to unparalleled disaster.’ Our modes of thinking—that is the key, yet we change them with the greatest difficulty to meet a new, entirely new, situation. We now have got the power to destroy our world. We can do it slowly by exploitation, tearing up the forests, polluting the seas, piling up nuclear waste and filling even outer space with the dustbins of our technology. Or we can do it quickly. A war no-one expects suddenly starts—confusion reigns, troops panic, a nuclear weapon is fired and the gate to Armageddon opens. This is not a panic scenario. With 50,000 nuclear weapons in the world today it is a perfectly realistic one. We have, in our mad arsenals, something like 6,000 times the fire power of the whole of the Second World War. A cruise missile, made to sound so nice and small and tactical, has a warhead about ten times that of the Hiroshima Bomb—itself over a thousand times more powerful than the largest bomb of the Second World War. Yet our MoD talks about using them ‘to stop the Russians at the eleventh hour’.

Years ago the United Nations, in several serious reports, made it clear that this nuclear deterrence on which we put such reliance cannot be a stable system of security.
