Are you aware of the utopian thinking that world government requires?No atomic weapons have been used since WW2.I shudder to think the N.Koreans and Iran will possess them.Mutually assured destruction worked during the cold war.I'm not sure rational beings will be making decisions in the future.Russell was a celebrated philosopher.He was a dedicated socialist.I don't believe in utopia.There are no perfect answers to human nature.There is road paved with good intentions and it isn't heaven.
Are you aware of the utopian thinking that world government requires? Of course I am. And so were the great scientists of that period. They had the example of the failure of the League of Nations. All the Europeans (and especially the Jews) knew how deep the hatreds and divisions ran. But they were desperate. Atomic arms raised the stakes too high.
My purpose, again, is to try to present the mind-set of these scientists. I believe if they co-operated or urged co-operation with the Russians it was this desperation which motivated them - not naive beliefs about the beauties of Soviet Communism.
