Military Ethics: Just War, Virtue, and Professional Standards

Just War Theory and Its Six Conditions

Peace, subsistence, liberty, and life are fundamental values in any civilization. When war occurs, these core values are placed at risk due to the inherent aggression that conflict brings. However, just war theory provides a framework that justifies wars under specific moral conditions. These conditions are divided into two categories: three conditions grounded in deontological (duty-based) ethics and three rooted in teleological (consequence-based) ethics.

The first three conditions rest on deontological principles. First, there must be a just cause for war, such as self-defense, protection of others, or corrective punishment. Second, the intention behind war must align with the just cause; any intention that deviates from this purpose undermines the legitimacy of justice. Third, legitimate state authority must exist and public declaration of war must occur before hostilities begin.

The remaining three conditions derive from teleological theory, focusing on outcomes and consequences. Fourth, war should only be undertaken as a last resort after all other alternatives have been critically evaluated. Fifth, there must be a reasonable probability that the war will resolve the conflict. Finally, and sixth, the benefits gained from war must outweigh the harm and damage it will cause. Together, these six conditions create a framework within which war may be morally justified (Lacewing p. 1).

Virtue Ethics Versus Deontological and Teleological Approaches

Virtue ethics, developed primarily by Plato and Aristotle, differs fundamentally from both deontological and teleological ethical theories. Rather than focusing on rules or consequences, virtue ethics centers on the character of the individual. Plato emphasized that individuals must be taught what is good through proper instruction, and that right instruction is more important than specific outcomes. Aristotle and later virtue ethicists argue that correct moral knowledge comes not from theoretical study alone, but from observing and learning from the actions of virtuous people.

The key distinctions are clear. First, virtue-based ethics relies on learning through observation of others rather than independent personal reasoning about ethical principles. Second, deontological (principle-based) ethics asserts that certain rules or duties apply universally to everyone, while teleological (consequence-based) ethics holds that an action is ethical only if it produces the greatest good for the greatest number. Virtue ethics operates on an entirely different principle: the golden mean.

The golden mean concept illustrates how virtue ethics works. Consider confidence: it exists on a spectrum with cowardice on one end, courage in the middle, and rashness on the other end. Courage is the virtuous mean. According to virtue ethics, knowledge of this golden mean can only be gained through careful observation and imitation of others' actions—a process that takes a lifetime to master. This approach emphasizes gradual character formation through apprenticeship rather than adherence to fixed rules or calculation of outcomes (Kem p. 4-5).

Ethical Relativism and Moral Dilemmas

Ethical dilemmas occur when a person faces a situation with no clear choice between right and wrong, but rather between two equally valid but contradictory values. This is fundamentally different from a difficult decision where the ethical answer is clear but requires moral courage to implement. An ethical dilemma proper exists only when two legitimate values stand in direct opposition, both being equally important yet mutually exclusive in that specific moment.

Several categories of ethical dilemmas recur across contexts: individual versus group interests, present benefits versus future benefits, factual accuracy versus loyalty, and fairness versus compassion. When an ethical dilemma falls into one of these categories, it can be evaluated using established ethical standards to guide a decision. By contrast, when a situation presents a clear distinction between right and wrong, it is not truly an ethical dilemma but rather a test of moral courage or strength of character.

The question of conventional ethical relativism—whether all valid moral principles are justified merely by cultural acceptance and no objective moral principles exist—must be examined in light of these distinctions. Ethical dilemmas, by their nature, reveal that not all cultural practices or accepted principles can be equally valid. When two values collide and both are genuine, the decision between them cannot rest solely on what a culture happens to accept; rather, the decision requires engagement with deeper ethical reasoning. Thus, pure cultural relativism fails to address the real complexity of ethical decision-making (Kem p. 2).

The U.S. Army as a Profession: Character and Trust

The United States Army maintains its status as a profession through reliance on value-based ethics and character development. The Army's leadership doctrine guides each soldier toward right action by developing individual character, ensuring that soldiers will make ethically sound decisions even in the most challenging circumstances. This approach mirrors virtue ethics: the focus is on building the character of the person, not simply creating rules.

The Army's leadership definition, encoded in the acronym LDRSHIP, captures this philosophy. The letters stand for loyalty, duty, respect, selfless service, honor, integrity, and personal courage. These are not mere rules imposed from above but virtues that leaders at all levels are expected to cultivate in themselves and model for those under their command. By emphasizing character and virtue, the Army seeks to maintain both its internal professional standards and its legitimacy in the eyes of the civilian population it serves (Kem p. 1-2).
