The people of this country may at last have faced up to the realities of all-out nuclear warfare. Russia's resumption of nuclear tests and the 100-megaton bomb have awakened us, for a brief moment, from the dream of deterrence. Even if this has meant only ratiier panicky discussion of “shelter morality,” it is good that we have looked out on the world with open eyes. Before world events permit us to return again to our slumbers, this moment should be seized; the opportunity to think through the moral and political dilemmas long inherent in our massive deterrence policy should not be allowed to slip from us.
