When Secretary General Hammarskjold’s invitation to address this General Assembly reached me in Bermuda, I was just beginning a series of conferences with the Prime Ministers and Foreign Ministers of Great Britain and of France. Our subject was some of the problems that beset our world. During the remainder of the Bermuda Conference, I had constantly in mind that ahead of me lay a great honor. That honor is mine today, as I stand here, privileged

Lyndon Baines Johnson: \We Shall Overcome\ Mr. Speaker, Mr. President, Members of the Congress: I speak tonight for the dignity of man and the destiny of democracy. I urge every member of both parties, Americans of all religions and of all colors, f rom every section of this country, to join me in that cause. At times history and fate meet at a single time in a single place to shape a turning
