And that is the most important topic on earth: peace

Commencement Address at American University, June 10, 1961

What kind of peace do I mean? And what kind of a peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children-not merely peace for Americans but peace for all men and women-not merely peace in our time but peace in all time.

Commencement Address at American University, June 10, 1963

Commencement Address at American University, June 10, 1963

Let us call a truce to terror. Let us invoke the blessings of peace. And as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.

Address to the United Nations General Assembly, September 25, 1961
