Regarding your original question about Yugoslavia's dissolution and subsequent wars, it's my understanding that at its base was a nexus of ethnic and religious tensions, as opposed to national identities.
I do think that upstart nations can gain a sense of national identity through warfighting. I don't know enough about the current conditions in the Balkans to say that that is the case there, though.
