Abstract Far-right populist leaders often take office promising a revolution in policies. They project themselves as counterpoints to other political competitors and defend radical positions regarding a set of issues. These contents may include nationalistic–chauvinistic measures, antienvironmental attitudes, conservative postures toward human rights, and religious leaning. According to our framework, though, leaders will only be able to pursue sharp foreign policy changes in pluralistic societies if, first, they win internal disputes at policymaking venues. Second, some policies will depend on external support or, at least, the non-imposition of unsurmountable obstacles. An acute foreign policy change may occur if such “battles” are won—home and abroad. Otherwise, a few incremental and superficial shifts are the maximum outcomes these leaders can get. A within-case study on Bolsonaro's Brazil provides useful evidence for our argument.
