Legitimacy is a condition based upon the perception by specific audiences of the legality, morality, or rightness of a set of actions and of the propriety of the authority of the individuals or organizations in taking them. The operational principle of legitimacy is closely associated with trust—the bedrock of the Army Profession. Legitimacy during stabilization has two aspects. One is the legitimacy of the host-nation government and is principally conferred by the local populace. The other is legitimacy of the mission which is derived from four factors: mandate, manner, consent, and expectations. Treating the local populace with dignity and respect is how leaders and Soldiers earn the legitimacy and trust of the host nation. Serving honorably, conducting operations ethically, effectively and efficiently to the extent possible is how the Army maintains the trust of the American people and our allies. The joint operations principle of legitimacy impacts every aspect of operations from every conceivable perspective. Legitimacy of the host-nation government and mission enables success characterized by conduct of stability operations.
