Across the globe, radical conservative political forces and ideas are influencing and even transforming the landscape of international politics. Yet IR is remarkably ill-equipped to understand and engage these new challenges. Unlike political theory or domestic political analyses, conservatism has no distinctive place in the fields’ defining alternatives of realism, liberalism, Marxism, and constructivism. This paper seeks to provide a point of entry for such engagement by bringing together what may seem the most unlikely of partners: critical theory and the New Right. Important parts of today’s New Right represent self-conscious appropriations of Critical themes and thinkers—turning them to self-declared “reactionary” ends. Developing outside the confines of the academy, these forms of thought have woven insights from across Critical theory into new and mobilizing forms of conservative ideology, seeking to link that ideology to social forces that play increasingly active roles in global politics. Our intention here is not to somehow blame Critical perspectives for the ideas of the New Right, either directly or by association. Rather, we seek to show how an engagement with Critical theory helps us understand the New Right, while also demonstrating some of the direct challenges the New Right poses for critical perspectives.
