In the future world the misuse of power, as implied in the term “power politics,” must not be a controlling factor in international relations. That is the heart of the principles to which we have subscribed. We cannot deny that power is a factor in world politics any more than we can deny its existence as a factor in national politics. But in a democratic world, as in a democratic Nation, power must be linked with responsibility, and obliged to defend and justify itself within the framework of the general good.
