Harry Truman actually said...

"Let this display of the flags of the United Nations symbolize our unity with our Allies both upon the battlefields of war and under the skies of peace."

"I urge the people of the United States on that day to fly the American Flag from their homes."

"Decent unemployment benefits would serve as a bulwark against postwar deflation."

"Let us observe this Flag Day by raising our Flag and beside it the flags of the United Nations."
