War is not merely a political act, but also a real political instrument, a continuation of political commerce, a carrying out of the same by other means." -Carl von Clausewitz, On War, 1832. Three main concepts of war stand out: war should be seen as an instrument of politics; the military objectives in war that support one's political objectives fall into two types: "war to achieve limited aims" and war to "disarm" the enemy; and the course of war will tend to favor the party with the stronger emotional and political motivations, but especially the defender.
