As a military man who has given half a century of active Service, I say in all sincerity that the nuclear arms race has no military purpose. Wars cannot be fought with nuclear weapons. Their existence only adds to our perils because of the illusions which they have generated. There are powerful voices around the world who still give evidence to the old Roman precept—if you desire peace, prepare for war. This is absolute nuclear nonsense.
