Rights and Liberal Interventionism in International Affairs

There is a distinct school of thought in our day which seeks to justify what has come to be called liberal interventionism in the affairs of other states.  These interventions are justified by an appeal to human rights with the concomitant view that it is the job of all states to guarantee basic rights and that sovereignty is purely an instrumental value.  A state which egregiously infringes rights loses its own right to sovereignty since the whole purpose of the state is the protection of rights.  This connects up with Christian and other religious ideas about just and unjust wars.
