The LAI’s theoretical organ The Anti-Imperialist Review and its editorial history represent a constituent source of militant reportage on global anti-imperialism between the two World Wars, as well as a rigorous effort to construct a conceptual framework within which the international communist movement could politically analyze how these phenomena were articulated within the broader international relations of force. The dead-ends and contradictory ideological and political shifts that the LAI had to navigate also point to the insurmountable problems of the anti-imperialist practice of Comintern-linked organizations.
