Military occupation is a step victors may take toward order and peace. Effective, prospectively directed occupation, whose purpose is peace, requires an agreement of minds and hearts, that is, concord, in St. Augustine's term, between occupants and natives, 1 Concord under occupation includes arrangements to which the defeated rationally acquiesces in the face of the occupant's superior force, and those to which the defeated agrees out of a desire for a reestablished tranquility.
