John Kennedy actually said...

"Only the President of the United States can place before the American people the unfinished business of our society."

"Secondly, how can we maintain the peace and maintain our own security around the world and strengthen freedom?"

"This is a contest between the concerned and the comfortable, and you have to decide what you are, comfortable or concerned."

"Our prestige is not based on what we say but what we do, relative to what our enemies do."
