Lyndon Johnson actually said...

"Every day and every hour and every mile was worth it."

"Yet all we have ever heard from the other side is that they renew their voice of hostility."

"You hear enough of the bad, you read enough of the bad, and you see enough of the bad on television, that you ought to know something about the good."

"Difficult days lie ahead of us in Vietnam, until the Communists change their minds about fighting."
