Abstract
This paper concentrates on the way Kant's distinction between duties of right and duties of virtue operates at the interstate level. I argue that his Right of Nations (V ölkerrecht) can be interpreted as a duty to establish a kind of interstate distributive justice (that is, as a duty to secure states in their independence and territorial possessions), which is called for to secure domestic distributive justice and to protect individuals' freedom and private property. Or at least this is 'ideal theory' for, as I specify, this cosmopolitan linkage is compromised by Kant's endeavour to accomodate the existence of non-republican states.
