"When the atomic bomb was dropped at Hiroshima and then Nagasaki, I was immediately asked... to give a talk... about atomic bombs. My talk, as I recall, was entirely on what the atom is, what nuclear fission is... But I kept giving these talks, and I realized that more and more I was saying, it seems to me that we have come to the time when war ought to be given up. It no longer makes sense to kill 20 million or 40 million people because of a dispute between two nations ... It no longer makes sense. Nobody wins. Nobody benefits from destructive war of this sort and there is all of this human suffering."

Joseph Rotblat – Nobel Peace prize 1995 (together with Pugwash conferences)Russel-Einstein Manifesto, 1995:“Above all, rememebr your humanity”

It's the psychology of war,' said Joseph Rotblat. 'Once we enter war, our moral values are thrown overboard. We are encouraged to kill people. Even people who in the past had been friends became, in our minds, our mortal enemies.'
