Last Sunday, Kosovo formally declared independence to the accompaniment of festive celebrations by the good citizens of the world's newest country. We can but wish them well as they chart a new course inside a new Europe free of the distracting conflicts that had ravaged the continent until the middle of the 20th century.

The two iconic cases of international intervention in 1999 were Kosovo and East Timor. Canada was involved in the first, Australia led the second.

As the recent attempted assassinations of East Timor's President Jose Ramos Horta and Prime Minister Xanana Gusmao show, the euphoria of independence is not enough to sustain the structures and practices of a civic community and viable polity. It would be naive to believe that centuries-old history of Serbian-Kosovar conflict has been brought to a closure. The Serbs venerate Kosovo as the cradle of their nationhood dating back to the war with the Ottoman Empire in 1389, which they lost. Their sense of victimhood and grievance has deep historical roots that will likely outlast Sunday's "setback."
