Strange offers a criticism of Krasner's realist position, drawing on her recent work and an understanding of structural power. She also offers brief critiques of political and economic liberalism as being essentially internally inconsistent, before suggesting that it is they rather than the 'societal' approaches that are having theoretical problems with recent developments in the international political economy. Realism and liberalism lack the heuristic power of her own (and others) structuralist approach. She concludes by arguing that all the many different groups of actors/interests in the international system must be recognised and analysed not just states.
