The UN recognized the independence of the 23 republics which previously formed part of Socialist federations of Czechoslovakia, Yugoslavia and the Soviet Union. However, he was hesitant to accept the sovereignty of some internal regions that these Republics had taken. Once it has been recognized the separation of the province of Kosovo to Serbia, then the legal possibility opens to other nations who exercise de facto independence seek to join the UN. These are the cases of the pro-Russian republics of Transdniestria in Moldova and Abkhazia and Georgia in South Ossetia. Washington accepted the independence of Kosovo because he wanted to undermine his Serbian rival and because it wants to enter the EU. However, it cannot accept split to friendly countries like Moldova and, especially, Georgia. Russia stands as the great protector of these three republics, although in its own territory it has repressed brutally to Chechnya when it declared its sovereignty. National self-determination is a principle that proclaim Bush and Putin but that both subordinated to its ambitions. Original author and source of the article.
