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.
Foreign relations of NATO
According to a NATO diplomatic source in August 2009 some key officials at NATO headquarters in Brussels were pushing hard for engaging Azerbaijan on the membership question. "Turkey, Romania, Italy, Poland, the United Kingdom and the Baltic states" are among the members backing a fast track for Azerbaijan's NATO membership. While President Ilham Aliyev has generally supported non-belligerency (though not neutrality due to the unresolved conflict with Armenia over Nagorno-Karabakh) since his rise to power in 2003, Azerbaijan has hosted NATO military exercises and high-profile meetings in 2009. The unresolved conflict over Nagorno-Karabakh would present a major roadblock to membership. Azerbaijan made its policy of not being aligned with a geopolitical/military structure official when it became a full member of the Non-Aligned Movement in 2011.
