NATO
New membership in the alliance has been largely from Central and Eastern Europe, including former members of the Warsaw Pact. Accession to the alliance is governed with individual Membership Action Plans, and requires approval by each current member. NATO currently has two candidate countries that are in the process of joining the alliance: Bosnia and Herzegovina and the Republic of Macedonia.
In NATO official statements, the Republic of Macedonia is always referred to as the "former Yugoslav Republic of Macedonia", with a footnote stating that "Turkey recognizes the Republic of Macedonia under its constitutional name". Though Macedonia completed its requirements for membership at the same time as Croatia and Albania, who joined NATO in 2009, its accession was blocked by Greece pending a resolution of the Macedonia naming dispute. In order to support each other in the process, new and potential members in the region formed the Adriatic Charter in 2003. Georgia was also named as an aspiring member, and was promised "future membership" during the 2008 summit in Bucharest, though in 2014, US President Barack Obama said the country was not "currently on a path" to membership.
Macedonia (region)
Republic of Macedonia, Croatia and Albania were qualified to join NATO and an invitation for those three countries was planned to be issued on the NATO summit in Bucharest (Romania), in April 2008. Before the beginning of the summit, the American president Bush said that NATO would make a historic decision on the admission of three Balkan nations: Croatia, Albania and Macedonia; and that the United States strongly supported inviting these nations to join NATO. However, during the summit NATO leaders decided not to extend a membership invitation to Macedonia because Greece vetoed the move after the dispute over the name issue. The Macedonian representative and negotiator with Greece in the name issue complained that the Republic of Macedonia was punished not because it had failed to fulfill NATO accession criteria, but because it had been trying to defend its national identity. The NATO leaders agreed to extend a membership invitation for Macedonia as soon as the name issue with Greece is resolved, but until now no progress has been made in the negotiations between the Republic of Macedonia and Greece to resolve the name issue.
