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.

On July 1, 2004, the Headquarters once again transitioned in a ceremony marking its designation to Component Command-Land Headquarters, Heidelberg. New structure is currently represented by 15 NATO nations, including its newest members Lithuania and Slovakia. This transformation to CC-Land HQ HD was part of a major NATO restructuring, and realized a fundamental change in headquarters mission and operations, as this headquarters turns its focus from one of six joint sub-regional command headquarters, to assume roles as one of only two land centric headquarters in the NATO command structure designed to provide expeditionary command and control at the operational level of conflict.
