Do international organizations represent the interests of the global citizenry? Or are they merely vehicles for the agendas of powerful nations and special interests? Thomas Zweifel explores this increasingly contentious issue, deftly blending history, theory, and case studies. Zweifel’s analysis covers both regional organizations (e.g., the EU, NAFTA, NATO, the AU) and such global institutions as the United Nations, the World Bank, and the World Trade Organization. With international organizations becoming perhaps the most appropriate—if not the only—forum for tackling myriad transnational challenges, his systematic study of how these organizations function is central to the study of both international relations and democracy in the 21st century.
