I'm not sure that Lenin meant the right of nations to self-determination to be a Kantian categorical imperative, outside of history. Rather he saw that it was a right that took on special significance in the light of the domination of imperialist powers. In that light he would have endorsed Yugoslavia's right to self-determination over the opportunistic agitation of those imperialist powers amongst the Yugoslav republic's disaffected minorities.
The key issue in judging the democratic content of these struggles is this: are the KLA fighting for independence, or for the subordination of the region to Western domination? I suggest the latter.
