What countries could join NATO in the future?

Who Could Join NATO Next?

With Finland officially joining in April 2023 and Sweden following in March 2024, NATO’s presence in Northern Europe has been significantly strengthened. These historic accessions came as a direct response to Russia’s increasing aggression, especially after its illegal invasion of Ukraine in 2022—which itself applied for fast-track membership just months after the invasion began, following the attempted annexation of its southeastern regions.

Ukraine’s path to membership remains a central topic within NATO discussions. While its application has been widely supported by member states, the process is complicated by ongoing conflict and the need for political and military reforms. Still, Kyiv’s Western aspirations are clear, and its eventual inclusion remains a strong possibility—if geopolitical conditions allow.

Beyond Ukraine, other nations have voiced their ambitions to join the alliance. Bosnia and Herzegovina has been engaged in partnership programs with NATO and has formally expressed its desire to become a member. However, internal political divisions and regional tensions continue to slow progress. Similarly, Georgia has long sought NATO membership, especially after its 2008 conflict with Russia. Despite a deepening partnership and military cooperation, full membership has yet to be scheduled.

Another name occasionally mentioned is Kosovo, which has expressed a desire to join the alliance. However, its path is complicated by the lack of universal recognition—some NATO members do not recognize Kosovo’s independence—making accession a sensitive diplomatic issue for now.

As Europe’s security landscape evolves, NATO’s role continues to expand. While not all aspirants will join soon, the door remains open—and for many, it represents more than defense. It’s a commitment to democracy, stability, and a shared future.
