It is immoral from almost any point of view to refuse to defend yourself and others from very grave and terrible threats, even as there are limits to the means that can be used in such defense.

As for total disarmament, there are almost 50,000 nuclear weapons in the world today; even if they were banned, not all would be destroyed.

Nevertheless, during the sixty years of the twentieth century many problems have come increasingly into the realm of acceptable public discussion.

Hopefully, nations will refuse to accept a situation in which nuclear accidents actually do occur, and, if at all possible, they will do something to correct a system which makes them likely.

From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.

Nuclear weapons are intrinsically neither moral nor immoral, though they are more prone to immoral use than most weapons.
