The week's news from the Balkans has been ominous. Serbia is making demands on Kosovo and its supporter, Albania. Serbia continues to see Kosovo as a threat to its national interest. The Russians have gone out of their way to express their support not only for the Serbs but also for the Serbs living in Bosnia. Last month, Russian President Vladimir Putin hosted Serbia's president in Moscow. Meanwhile, the U.S. friendship with Albania is deep, making the Serbian claim on Kosovo even more dangerous. Far less ominous but no less important, Turkish President Recep Tayyip Erdogan held a campaign rally last month in Sarajevo, the predominantly Muslim capital of Bosnia and home to a large number of Turkish expat voters, to win their support and to show voters at home that Turkish influence was spreading into the Balkans.
