The documents obtained by the Organised Crime and Corruption Reporting Project (OCCRP) suggests that Russia has played a very invasive role in the countries of former Yugoslavia, also to prevent them from being too involved in the gravitational orbit of NATO. The Guardian also comes to very similar conclusions. The most striking example in this sense is the one of Macedonia, where the country’s Social Democrat leader, Zoran Zaev, was sworn in as prime minister, after six months of political crisis. He, who is part of a center-left coalition supported by two ethnic Albanian groups, affirmed that he wants to fight corruption and want to bring Macedonia into NATO. The Macedonian nationalists have given rise to very violent protests against him. This, according to studies, is part of some intelligence operations triggered by Russia since 2008 to prevent the Balkans from approaching too much NATO. But The Guardian said that on NATO, the Kremlin has experienced setbacks. In April, Montenegro’s parliament voted to become the military alliance’s newest member. Bosnia and Herzegovina are candidates for entry. Even Serbia has deepened ties with NATO, even if the resentment many Serbs feel towards the alliance is not easy to hide because of the war of 1990s.
