Lyndon Johnson actually said...

"Whatever we are doing in faraway places--many with strange-sounding names--we are doing it not for power, not for territory, not for dominion, or not for influence."

"We must do whatever must be done to insure our success."

"Once our promise is broken in one place, even though it is a little country called South Viet-Nam, America's promise is worthless in all places."

"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."
