Abstract

In this chapter, it is argued that although cosmopolitanism is sceptical about the value of national self-determination, it nevertheless has the resources to justify the claim that individuals whose community is attacked unwarrantedly have the right to use force in its defence. The argument proceeds by distinguishing between three different kinds of aggression and identifies when combatants, when invited to sacrifice the collective goods of sovereignty and territorial integrity, are entitled to use force against rights-violators.
