In this second episode of my summary series, I address the Nature of War. That nature is violence directed at an opponent to coerce him to submit to your will. This violence has always been the nature of war and it will always be so. Further, this violence must be so painful to your opponent that he will prefer submitting to your will rather than continuing to resist. How you apply that violence and where the pain must be applied changes with time, technology, and culture. Further, the tools to apply this pain are not just kinetic, or direct military action. Economic pain can be just as important as military force. So too is information directed towards increasing fear of pain in the opponents’ population, its leaders, and your opponents’ friends. What makes war different from other forms of violence is its political nature. This violence is directed towards achieving a political end state. Without directing military force to a clearly defined political objective military success is still possible but will, more than likely, end in strategic failure.   For more information refer to Episode 7 of this series, “What is War;” Episode 8: “The Natural Laws of War;” Episode 42: “All Successful Wars Are Alike;” and Episode 43: “Ways to Lose a War.”   Reference: Clausewitz, C., On War, (Michael Howard and Peter Paret Ed.
