"Where an 'act of state' registers an unseaworthy oil tanker, we should create state liability to clean up the mess that results from its sinking. We should seize these vessels when they enter our waters, and impound them until they are fixed. Better yet, we should just impose our rules on these countries to prevent them from registering such ships in the first place, and make sure they are enforcing a high standard. Global interest, global damage, global rule." Comment on this statement considering jus cogens (universal norms), the act-of-state doctrine, and sovereign independence of states.
