Lyndon Johnson actually said...

"Let no citizen that is secure in his own liberty ever forget how precious it is and how brave we must be if we are to keep it."

"You must give the hours of your life, and the fruits of your learning, and the courage of your spirit, and the substance of your home to those in need in every continent of the earth."

"Our role will be vital, but we hope that all other industrialized nations, including the Soviet Union, will participate."

"This is an occasion to make any President very proud and very glad"
