Lyndon Johnson actually said...

"But we are enemies always of human privation and prejudice--and we shall not rest until justice prevails throughout the world against these adversaries."

"I hope, sir, when you return, that you will take with you this message."

"In America today, this generation of Americans is determined to fulfill that ideal by all that we do in the world and by all that we do here at home."

"We must spare no effort in learning how to desalt these waters economically."
