Lyndon Johnson actually said...

"You cannot be in such a place, among such men, without feeling grief well up in your throat, without feeling grateful that there is such courage among your own countrymen."

"I told His Holiness that America welcomed his efforts to bring an end to the strife and sorrow."

"I wanted to promise him--as I have promised you, my fellow Americans--that the disappointments we had known in the past would never deter us from again trying any reasonable route to negotiations."

"I told them that I wished I could bring them something more--some part of the pride you feel in them, some tangible symbol of your love and concern for them."
