As the international community struggles to make sense of the post-cold war world, Professor Michael W. Doyle urges us to look again at the classical theorists. Ways of war and peace lays out three theorical schools of thought-Realism, Liberalism, and Socialism-and reintroduces the reader to Thucydides, Rousseau, Locke, Marx, and others. The enduring theories are explained and explored and then applied with insight to today's fundamental international dilemmas. Althoug no one school has all the answers, Doyle's sharp analysis maintains that we do have the theorical tools to meet today's challenges.
