 Outlaw states are non-compliant: they threaten the peace by attempting to expand their power and influence, or by violating the human rights of those within their territory. The principles of the law of peoples allow peoples to fight these outlaw states in self-defense, and to take coercive actions against them to stop their violations of human rights. In any military confrontations with outlaw states, peoples must obey the principles of the just prosecution of war, such as avoiding direct attacks on enemy civilians in all but the most desperate circumstances. The aim of war, Rawls says, must be to bring all societies to honor the law of peoples, and eventually to become fully participating members of international society.
