The author, who is both international lawyer and political scientist, addresses the gap between the practitioners of those two trades as they confront contemporary international relations and the imperatives of American foreign policy. He has little use for the "legal positivists" of the old school but even less for the Machiavellians (Kissinger, Brzezinski, et al.) whose creed is realism and the politics of power. His main argument is that international law and international organizations, far from being peripheral to foreign policy, offer the only hope for peace and security. In a lengthy critique of U.S. foreign policy on this theme he makes some telling points, but also others that are overblown and even approach the ridiculous.
