Lyndon Johnson actually said...

"This is the firm and the irrevocable commitment of our people and our Nation, whatever the risk and whatever the cost."

"Today, in a figurative sense if not a literal one, I am very proud and very happy on behalf of all the American Nation to salute you as a distinguished officer and a most distinguished American."

"That alliance is one of our great assurances that the failures of the first half of our century will not be repeated in the last half of our century."

"We have no desire whatever to expand that conflict."
