The potential arrest of Venezuelan President Nicolas Maduro by the US raises significant questions about international law and head-of-state immunity. International law, including the UN Charter, generally prohibits the use of force against a state's political independence, with exceptions for self-defense or UN Security Council authorization. Sitting presidents typically possess immunity from foreign arrest, a principle designed to maintain stable international relations. While the US may cite universal jurisdiction or the fight against narco-terrorism, these justifications are debated as grounds for unilateral military action against a sovereign leader.
