When the International Court of Justice (ICJ) released its advisory opinion regarding the legality of Kosovo's unilateral declaration of independence (UDI) on 22 July 2010, Serbia was not the only State to express its dissatisfaction with the outcome. The broader significance of the ICJ's finding that Kosovo's UDI in 2008 did not violate international law has profound relevance for other States. The United States and its allies claim that Kosovo's situation is unique and does not serve as precedent, but other nations facing separatist movements within their own borders may have reason to be concerned.
