There is a tendency, especially among certain liberals and many who call themselves idealists, to believe that the subject of power in the international world should not be spoken of except in terms of moral disapproval. They consider that studies concerning the organization of peace and security should deal only with the ideals of our democratic civilization and visions of a better world order in which power will play no part.

As a matter of fact, political ideals and visions unsupported by force appear to have little survival value. Our Western democracies certainly owe their existence and preservation to the effective use of power, either on their own part or on the part of an ally.
