Excerpt 1:
“It would be an unspeakable tragedy if these countries, which have struggled so long against overwhelming odds, should lose that victory for which they sacrificed so much. Collapse of free institutions and loss of independence would be disastrous not only for them but for the world. . . . “In addition to funds, I ask the Congress to authorize the detail of American civilian and military personnel to Greece and Turkey, at the request of those countries, to assist in the tasks of reconstruction, and for the purpose of supervising the use of such financial and material assistance as may be furnished.”

Excerpt 2:
“As we meet here today, we stand on the threshold of a new era of peace in the world. . . . This past year saw far-reaching results from our new policies for peace. By continuing to revitalize our traditional friendships, and by our missions to Peking and to Moscow, we were able to establish the base for a new and more durable pattern of relationships among the nations of the world. . . . Let us continue to bring down the walls of hostility which have divided the world for too long, and to build in their place bridges of understanding — so that despite profound differences between systems of government, the people of the world can be friends. Let us build a structure of peace in the world.”
