For all it spends on wars, America has not done well fighting them since World War II. Subsequent conflicts have often amounted to “moral routs” because large segments of the country have questioned why their leaders entered them. Military professionals may see morality as a distraction, yet recognizing its relevance to the citizenry and the world is also profoundly pragmatic. Modern democracies must marshal their populations behind a banner of legitimacy. Thus, today’s professional military education and training must provide the principles and role models to buttress the Nation’s grand strategy and secure the admiration and cooperation of allies. Design methodology can help prepare the necessary “moral symmetry” to ensure meaningful victory and lasting peace.
