If nuclear weapons are a dreadful threat and mankind cannot afford war any longer, then mankind cannot afford statism any longer. Let no man of good will take it upon his conscience to advocate the rule of force—outside or inside his own country. Let all those who are actually concerned with peace—those who do love man and do care about his survival—realize that if war is ever to be outlawed, it is the use of force that has to be outlawed.
