This paper examines what prevents us from legally enforcing the moral imperative of protecting human rights during military operations carried out for distinctly humanitarian purposes. The answer, I argue, lies not in familiar objections to bringing the law into greater congruence with morality, but in international law's indeterminacy regarding the use of force. Preserving stability within the nascent international legal system comes at the cost of a law that eschews the protection of individual rights even in cases in which the (...) protection of human rights is what justifies military action. The tension between state sovereignty and the protection of human rights thus not only generates well-known controversies about the lawfulness of military intervention. It also prevents us from devising laws to protect human rights during wars whose very purpose it is to stop human rights violations. Protecting human rights during humanitarian interventions may thus remain an undertaking as quixotic as it is morally urgent. (shrink)
