Four countries in North America, Central America, Europe and the Antipodes – namely Canada, Mexico, Norway and Australia – have been selected in order to explore the complexities of globalization from the perspective of the semi-periphery. Opening chapters examine the international institutions, including the North America Free Trade Agreement, the World Trade Organization and the European Union, which now amount to a quasi-constitutional conditioning framework for middle powers under globalization. In the second part, contributors detail the pressures with which these countries have to cope and consider their ability to pursue policies appropriate to the needs and democratically defined goals of each. And in the concluding part, after discussing the new economic, political and social issues of ‘governing under stress’, they appraise the possibilities for middle powers to chart distinctive national courses in the face of globalization’s constraining challenge.
