Daily quote by International relations

• We must distinguish between military and political power. Political power is a psychological relation between those who exercise it and those over whom 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 these.
  • Hans Morgenthau, Politics Among Nations (1948).
