These are three of the central issues of the Great Society. While our Government has many programs directed at those issues, I do not pretend that we… - Lyndon B. Johnson

First, we have worked to avoid war by accident or miscalculation. I believe the American people should know the steps that we have taken to eliminate the danger of accidental attack by our strategic forces, and I am going to talk about that tonight. The release of nuclear weapons would come by Presidential decision alone. Complex codes and electronic devices prevent any unauthorized action. Every further step along the way--from decision to destruction--is governed by the two-man rule. Two or more men must act independently and must decide the order has been given. They must independently take action. An elaborate system of checks and counter-checks, procedural and mechanical, guard against any unauthorized nuclear bursts. In addition, since 1961 we have placed permissive action links on several of our weapons. These are electromechanical locks which must be opened by secret combination before any action at all is possible, and we are extending this system. The American people and all the world can rest assured that we have taken every step that man can devise to insure that neither a madman nor a malfunction could ever trigger nuclear war.

Nineteen years ago President Truman announced "the force from which the sun draws its power has been loosed." In a single, fiery flash the world as we had known it was forever changed. Into our hands had come much of the responsibility for the life of freedom, for the life of our civilization, and for the life of man on this planet. And the realities of atomic power placed much of that burden in the hands of the President of the United States.

World peace depends upon reason, on restraint, on negotiation, and on responsibility. We must move forward on many fronts. We must continue to strengthen the United Nations. We must strengthen and expand the Peace Corps. We must build new bridges, new bridges to the friendly peoples of Eastern Europe. We must, most of all, take this world out from under the shadow of a poisonous toadstool cloud. We want our children to say that this was the generation that split the atom, and this was the generation that united all men in peace. We are a powerful nation, but we are humble before our God. We believe that man has made his own problems, but that man can solve them.
