A fresh assessment of the neoliberal political economy behind Canadian foreign policy from Afghanistan to Haiti, Joining Empire establishes Jerome Klassen as one of the most astute analysts of contemporary Canadian foreign policy and its relationship to US global power. Using empirical data on production, trade, investment, profits, and foreign ownership in Canada, as well as a new analysis of the overlap among the boards of directors of the top 250 firms in Canada and the top 500 firms worldwide, Klassen argues that it is the increasing integration of Canadian businesses into the global economy that drives Canada's new, increasingly aggressive, foreign policy. Using government documents, think tank studies, media reports, and interviews with business leaders from across Canada, Klassen outlines recent systematic changes in Canadian diplomatic and military policy and connects them with the rise of a new transnational capitalist class. Joining Empire is sure to become a classic of Canadian political economy.
