What would happen to our understanding of international law and its relationship with violence if we collapsed the distinction between our supposedly post-colonial ‘present’ and its colonial ‘past’; between the sovereign spaces of the twenty-first century global order, and the integrated, hierarchical space of fascist imperialism? I respond to this question through an investigation into the physical contours of a precise ‘imperial location’: 30°31′00″N, 18°34′00″E. These co-ordinates refer to a point on the sea-edge of the Sirtica that is occupied today by the Ra's Lanuf oil refinery, one of Libya's three most important such facilities. In the late 1930s, however, during Libya's period of fascist colonial rule, this was the point at which a state-of-the-art motorway, the Via litoranea libica, was crossed by a giant triumphal arch, the Arco dei Fileni. Through a chronotopic reading of the temporal, spatial and interpellative aspects of this point, its architecture and its history, I suggest that fascist lawyers, officials and intellectuals accepted a horrifying truth about the relationship between international law and violence – a relationship that twenty-first century doctrinal international law is loath to confront, concerning the inherently expansionist logic of the sovereign state, and the inevitably hierarchical ordering of the ‘international community’ which stems from it.
