Lyndon Johnson actually said...

"We defend, and I intend to defend, the right of everyone to disagree, if he wants to, with everything that we urge or everything that we do."

"Our safest guide to what we do abroad is always take a good look at what we are doing at home."

"Nor, may I say, do we have a different face for Moscow, Peking, or Hanoi."

"I am very happy to be here."
