We know that sacrifices lie before us and that we must pay a price for the heroic act of being a vanguard nation. We leaders know that we must pay a price for the right to say that we are at the head of a people, which is at the head of the Americas. Each and every one of us must pay his exact quota of sacrifice, conscious that he will get his reward in the satisfaction of fulfilling a duty, conscious that he will advance with all toward the image of the new man dimly visible on the horizon.
