Unfortunately, the obvious futility of war has not brought peace to the world. For centuries mankind has longed for a world without war; now that the need is so urgent, with nuclear nations having access to more destructive power than any opponent could tolerably absorb, we seem ill prepared to live in peace with each other.
Here is a strange enigma: a world without all-out war or real peace, a world held in place by a doctrine of nuclear deterrence that appears to lack credibility.
However much the doctrine of deterrence is deemed necessary politically or militarily, it raises serious moral questions. It seems that the technological progress resulting from the immense release of atomic energy is as yet unmatched by a corresponding moral capacity for realizing and maintaining peace.
