Capitalism,uneven and combined development and the transhistoric

What is the status of Trotsky's notion of uneven and combined development within Marxist theory and how might it be fruitfully employed by Marxists in international relations? Is uneven and combined development a transhistoric general abstraction or does it need rooting in the relations, processes, tendencies and counter-tendencies of a particular mode of production? This article rejects Justin Rosenberg's recently drawn conclusion that uneven and combined development is usefully understood as a transhistoric general abstraction that potentially offers the basis of a transhistoric theory of the international. Instead it questions the value of transhistoric categories for Marxist theory and pursues the argument that uneven and combined development is best understood within the relations, processes and tendencies of the capitalist mode of production, arguing that capitalist social relations and political forms are historically unique in their capacity to generate both combination and unevenness.
