From Realism to the Liberal Peace

Twenty years ago realists, emphasizing the influence of the international system and working in the humanistic tradition, dominated research on the causes of war. Today, liberal theories occupy center stage, and political scientists rely on statistical analyses of pairs of states through time. Epidemiological studies of over 12,000 dyads, 1885-2001, using a liberal-realist model of interstate conflict confirm the pacific benefits of democracy and economic interdependence. Development is also beneficial. Key elements of realism do receive statistical support; but democracy and trade are at least as influential as power, and they are more amenable to social engineering. Realism does not provide a path to world peace. The best hope is continued liberal reforms: the expansion and deepening of democracy and capitalism and the inclusion of more countries in the international economic system. Fortunately, globalization has advanced rapidly in recent decades, making for a generally optimistic prognosis.
