better not to have them at all, is not it?

Sir Józef Rotblat-the only physicist to leave Manhattan Project on moral grounds when it was clear Germany wouldn't be able to build the bomb. One of the signatories of the Russel-Einstein Manifesto and co-founder of the Pugwash movement.The man who devoted his long and fruitful life to promoting nuclear disarmament, investigating the detrimental effects of nuclear radiation on human health and informing the public opinion about it as well as researching ways of using radiation for beneficial medical purposes. His efforts and work were admired by the scientific community worldwide. In 1995, together with the Pugwash Movement, he received the Nobel Peace Prize. If you're interested, I recommend a Canadian documentary, "The Strangest Dream."
