For some years I have spent my time on exactly these questions - both in thinking about ways to prevent war, and in thinking about how to fight, survive, and terminate a war, should it occur.

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.

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.

Many people believe that the current system must inevitably end in total annihilation. They reject, sometimes very emotionally, any attempts to analyze this notion.

For if enough people were really convinced that growth should be halted, and if they acted on that conviction, then billions of others might be deprived of any realistic hope of gaining the opportunities now enjoyed by the more fortunate.

New developments in weapon systems during the 1950s and early 1960s created a situation that was most dangerous, and even conducive to accidental war.

Nuclear war is such an emotional subject that many people see the weapons themselves as the common enemy of humanity.
