The great Dutch philosopher Grotius, one of the founders of modern international law, wrote that foreign humanitarian intervention was lawful to “to stop the maltreatment by a state of its own nationals when that conduct is so brutal and large-scale as to shock the conscience of the community of nations.” I found the quote in a secondary source (Commentary magazine). Does anyone know the original cite? The quote does not appear in the law review database in Westlaw, nor in the Allcases database.
