Let us accept (as I do) the principle that national minorities have the right to self-determination within lopsided multi-ethnic states; e.g. Croats and Kosovars seceding from Yugoslavia, Scots from the UK, Georgians from the Soviet Union etc.
Awkward question no. 1: On what principle can we deny, once Croatia, Kosovo, Scotland and Georgia have come into being, the right of Krajina Serbs, of Mitrovica Serbs, of Shetland Islanders and of Abkhazians to carve out, if they so wish, their own nation-states within the newly independent nation-states in the areas where they constitute a clear majority?
Awkward question no. 2: On what principle does a western liberal deny the right of Chechens to independence from Russia, but is prepared to defend to the hilt the Georgians’ or the Ukrainians’ right to self-determination?
