Dusan Prorokovic, Serbia’s state secretary for Kosovo, has said that his country might use force to maintain its sovereignty. Even if the government hesitates, ultranationalist groups might push Prime Minister Vojislav Kostunica to send in troops: the current UN presence in Kosovo is very thin (only 40 “military observers” and 2,116 policemen) but the stationing of 15,000 NATO troops could make any armed clash very dangerous.
