It is a common observation that the theory and practice of international law are far apart. Richard Falk, for example, begins his 1970 book by chastising international legal theorists for failing to “provide adequate guidelines for evaluating particular decisions”.2Likewise, Louis Henkin asserts that, “Lawyer and diplomat are engaged in a dialogue de sourds. Indeed, they are not even attempting to talk to each other, turning away in silent disregard.”3
