In the wake of the Cold War, as the international community struggles to accommodate change, the author of this study directs our attention to the classic theorists, Thucydides, Rousseau, Locke and others. He explores their enduring theories, and recommends that they be applied to today's fundamental international dilemmas. Although no one school has all the answers, this analysis maintains that history has provided the theoretical tools to meet modern challenges, and that great political minds of the past can still guide modern politicians through the confusion of current events.
