Interests are not reducible to power: donnelly- in certain circumstances it may be unwise to pursue human rights, but that must be determined empirically, case by case. Realists are not entitled to categorically exclude hr as a legitimate goal of fp: the statist (legalist) argument. Ir is structured around the principle of sovereignty. Sovereignty in turn implies nonintervention in the internal affairs of other states. Hr have become legitimate subjects in ir because sovereign states have chosen to make them so: the weakness of existing international implementation and enforcement mechanisms (ch. 8) might allow statists to argue that incorporating hr into fp still contravenes the fundamental principle of non intervention, but numerous instruments of fp (eg, diplomatic representations and granting/ withdrawing preferential trade agreements) do not involve intervention. Such means may be used on behalf of hr as legitimately as they are used on behalf of other goals of hr.
