"when we talk of an open foreign policy we are seeking to establish the fact that the entire world is the stage upon which a country, however small, pursues this perception of self-interest. Nor does one have to conclude that self-interest is either an immoral or an amoral phenomenon. National self-interest for example, leads no wise man into war. War has often been the resort of fools like Mussolini or knaves like Hitler. They shared a common fate. And even successful wars of aggression set in train forces that undo the temporary advantage that they may confer. The only wars that are morally justified in history are those dedicated to national liberation where it is clear that no other method can succeed. Therefore a policy of enlightened self-interest will commend to any intelligently-led nation the conclusion that peace is in every man's interest in the end. Hence every country, and Third World countries even more so, has a tremendous investment in the success of the United Nations. But even as a supporter of the United Nations, it is also important that our foreign policy reflect a clear adherence to principle and the expression of those principles in the councils of the United Nations...The commitment must be to principle but tempered with a cautious recognition that many of the issues of international politics bristle with difficulty. In fact, it is the very complexity of these problems and the tensions that they create in the world that makes it so imperative that the United Nations itself survive and increase in influence and strength in the world. Hence a foreign policy must include a concern for everything that affects peace in the world which in turn implies a constant vigilance about international relations generally. (3: Foreign Policy)"
