Peace in our time, Peace in all time.
 
I have chosen this time and place to discuss a topic on which ignorance too often abounds and the truth too rarely perceived. And that is the most important topic on earth: peace. 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, and the kind that enables men and nations to grow, and to hope, and 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.
