No issue of contemporary international relations has greater apparent importance than conflicts arising from the gap between rich and poor societies in our interdependent world. Professor Tucker's lucid, forceful, unorthodox and important argument should continue the debates engendered by his earlier essays on this subject. To try to induce greater equality into international relations, the author insists, will be quixotic and counterproductive. Few would dispute Tucker's general thesis that a world of states will remain unequal. Many, however, will disagree with his major arguments about the distinctions between domestic and international affairs and the disutility of the rich trying to coopt or satisfy the poor.
