Ukraine’s relationship with the North Atlantic Treaty Organization (NATO) has undergone significant changes since its independence in 1991. Initially focused on cooperation, Ukraine has increasingly sought full membership, particularly following the Russian incursions of 2014 and 2022.

Early Cooperation and Neutrality

Following the dissolution of the Soviet Union, Ukraine began engaging with NATO in 1991. Throughout the 1990s and 2000s, Ukraine aimed to strengthen ties with the alliance although maintaining a neutral status. In 1994, Ukraine joined NATO’s Partnership for Peace program, and the NATO-Ukraine Commission was established in 1997 to foster the relationship.

Further deepening cooperation, Ukraine joined NATO’s Intensified Dialogue program in 2005. At the 2008 Bucharest summit, NATO indicated that Ukraine would eventually join the alliance, but stopped short of offering a Membership Action Plan.

A Shift Towards Membership

A pivotal moment occurred in 2014. Following Russia’s occupation and annexation of Crimea, and the subsequent conflict in eastern Ukraine, the Ukrainian parliament voted to seek NATO membership. This commitment was further solidified in 2018 when Ukraine enshrined this goal in its constitution.
