Unlike many students of normative theory in international relations, he has been reluctant to judge one side in a dispute entirely right and the other irrevocably wrong, granting instead that both may have some claim of justice which they might press too far if unopposed. This belief has led in turn to Thompson’s consistent position that ethically tolerable outcomes in international politics are more likely to be achieved through a counterbalancing of power than through moral exhortation.
