Populism, nationalism and revisionist foreign policy

Over the past decade, we have seen the rise of populist nationalist heads of state across a number of important electoral democracies - all of whom have made some version of the promise to make their countries 'great again'. However, scholars are divided over whether these leaders' sometimes bombastic rhetoric has consistent or predictable effects on state foreign policy. This article introduces a framework for mapping the effects of populism and nationalism in foreign policy. In doing so, it draws on Essex School discourse analysis and sociological frame analysis to argue that representational crises at the sub-state level increase the popular resonance of 'sovereigntist frames' that diagnose the causes of perceived gaps in representation of the 'authentic' sovereign community at the international level and enjoin chief executives to resolve these gaps through revisionist foreign policy practices. The ethno-nationalist master frame prescribes policies and practices of lateral revisionism (conflict with neighbours or rival states), the populist frame prescribes systemic revisionism (conflict with allies and the international 'establishment'), while the ethno-populist frame prescribes omni-revisionism (conflict with both). The article illustrates the effects of these disparate sovereigntist movements across three paired case-studies drawn from Europe, Latin America and the United States. It concludes that nationalism has greater destructive effects for the international system when combined with populism, demonstrating the importance of distinguishing nationalism and populism conceptually in order to isolate their separate and combined effects on foreign policy.
