Quotations

International politics, like all politics, is a struggle for power.

Politics Among Nations (1948), p. 13

When we speak of power, we mean man's control over the minds and actions of other men.

Politics Among Nations (1948), p. 13

Political power is a psychological relation between those who exercise it and those over which it is exercised. It gives the former control over certain actions of the latter through the influence which the former exert over the latter's minds. That influence may be exerted through orders, threats, persuasion, or a combination of any of those.
