Welcoming Hegel's idea of reconciliation as akin to his own enterprise of public reason, Rawls drew the line at his vision of the international realm as a domain of violence and anarchy, in which contention between sovereign states was bound to be regulated by war. Habermas's gesture enlisted Hegel, on the contrary, as a patron of cosmopolitan peace. The first could not square his Law of Peoples with the lawlessness of Hegel's states, the second could only enrol Hegel for pacific progress by turning him philosophically inside out. Bobbio, by contrast, could take the measure of Hegel's conception of world history, as a ruthless march of great powers in which successive might founds overarching right, and invoke it in all logic to justify his approval of American imperial violence. Law was born of force, and the maxim of the conqueror – prior in tempore, potior in jure.
