 In the last two decades, the issues of nationalism have been increasingly integrated into the debate about the international order (see the entries on  globalization  and  cosmopolitanism).  The main conceptual link is the claim that nation-states are natural, stable, and suitable units of the international order. A related debate concerns the role of minorities in the processes of globalization (see Kaldor 2004). Moreover, the two approaches might ultimately converge: a multiculturalist liberal nationalism and a moderate, difference-respecting cosmopolitanism have a lot in  common.[26]
