The task of building the peace lies with the leaders of every nation, large and small. For the great powers have no monopoly on conflict or ambition. The cold war is not the only expression of tension in this world — and the nuclear race is not the only arms race. Even little wars are dangerous in a nuclear world. The long labor of peace is an undertaking for every nation — and in this effort none of us can remain unaligned. To this goal none can be uncommitted.

Moreover, the Congress adopted a resolution expressing its support of this declared policy. Despite this, the rapid development of long-range missile bases and other offensive weapons systems in Cuba has proceeded. I must tell you that the United States is determined that this threat to the security of this hemisphere be removed. At the same time, I wish to point out that the action we are taking is the minimum necessary to remove the threat to the security of the nations of this hemisphere. The fact of this minimum response should not be taken as a basis, however, for any misjudgment on your part.

But I think the American people expect more from us than cries of indignation and attack. The times are too grave, the challenge too urgent, and the stakes too high — to permit the customary passions of political debate. We are not here to curse the darkness, but to light the candle that can guide us through that darkness to a safe and sane future. As Winston Churchill said on taking office some twenty years ago: if we open a quarrel between the present and the past, we shall be in danger of losing the future. Today our concern must be with that future. For the world is changing. The old era is ending. The old ways will not do. [...] It is a time, in short, for a new generation of leadership — new men to cope with new problems and new opportunities.
