What is a key constraint on the international promotion and enforcement of human rights?

• A. State sovereignty
• B. Universal jurisdiction
• C. Extraterritorial reach
• D. Military intervention rules

Answer: (A)

State sovereignty is the key constraint because a state has the final say over what happens within its borders, and international efforts to promote or enforce human rights must operate with the state's consent and respect for its jurisdiction. International norms exist, but enforcement isn’t automatic: treaties typically require ratification and domestic implementation, and outside actions—whether monitoring, criticism, or intervention—often depend on the state’s agreement or on a Security Council mandate. This means genuine, widespread enforcement rests on diplomacy, incentives, and cooperative arrangements rather than unilateral imposition. Other ideas describe tools or mechanisms that can occur in certain contexts, but they don’t override the overarching limit that states control what happens inside their territory unless they consent.
