We live in a land made of ideals, not blood and soil. We are the custodians of those ideals at home, and their champion abroad. We have done great good in the world. That leadership has had its costs, but we have become incomparably powerful and wealthy as we did. We have a moral obligation to continue in our just cause, and we would bring more than shame on ourselves if we don’t. We will not thrive in a world where our leadership and ideals are absent. We wouldn’t deserve to.
