Lyndon Johnson actually said...

"We know that we must find some way, somehow, a path to peaceful settlement."

"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."
