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.
Ukraine–NATO relations
Relations between Ukraine and North Atlantic Treaty Organization (NATO) started in 1994. Ukraine applied to join the NATO Membership Action Plan (MAP) in 2008. Plans for NATO membership were shelved by Ukraine following the 2010 presidential election in which Viktor Yanukovych, who preferred to keep the country non-aligned, was elected President. Amid the Euromaidan unrest, Yanukovych fled Ukraine in February 2014. The interim Yatsenyuk Government which came to power, initially said, with reference to the country's non-aligned status, that it had no plans to join NATO. However, following the Russian military invasion in Ukraine and parliamentary elections in October 2014, the new government made joining NATO a priority.
