The rise of the radical ‘New Right’ (NR) across much of the global political landscape is one of the most striking political developments of recent years. This article seeks to foster international theory’s critical engagement with the NR by providing an overview of its thinking about world politics and the challenges it presents. We argue that in many ways international theory is in fact uniquely positioned to provide such an engagement, and that it is essential that international theory comes to terms more fully with its political vision and theoretical claims if it is to engage effectively with this increasingly potent and often deeply troubling intellectual and political movement.
