"In 1945, on the 12th day of April, we were in the midst of two of the most terrible wars that have ever been fought."
"We are going to maintain the peace and make the United Nations a going and militant organization for the welfare of the world as a whole."
"The kind of peace we seek cannot be won at a single stroke or by a single nation."
"And I know very well that is exactly what we are going to do."
