In Wilsonianism , American foreign relations specialist Lloyd E. Ambrosius has compiled his published and unpublished essays on Woodrow Wilsons liberal ideology and statecraft during and after World War I. Although the president failed in his pursuit of a new world order, his legacy of Wilsonianism - the principles of national self-determination, economic globalization, collective security, and progressive historicism - continued to shape U.S. foreign relations throughout the American Century. Ambrosius examines the American roots of Wilsons liberal internationalism, the dilemmas and contradictions in his principles, and the problematic consequences of U.S. efforts to implement Wilsonian ideals without fully appreciating the worlds cultural pluralism as well as its economic and political interdependence. Offering a pluralist variant of the realist tradition in international relations, Ambrosius stresses the centrality of power; but maintains that culture and political economy as well as military strength determine the balance of power within and among nations or empires. Consequently, he concludes, making the world safe for democracy has been more problematic in practice, both at home and abroad, than proclaiming Wilsonian principles in the abstract.
