Ukraine’s interest in joining NATO has been longstanding, with its aspirations formalized in its constitution in 2019. At the 2008 Bucharest Summit, NATO agreed that Ukraine would eventually become a member, but no specific timeline or Membership Action Plan (MAP) was provided.
Pre-Invasion Developments
In the months leading up to Russia’s February 2022 invasion:
- NATO and Ukraine intensified their partnership, building on cooperation that had deepened since Russia’s 2014 annexation of Crimea.
- Tensions escalated as Russia massed troops near Ukraine’s borders in late 2021.
- NATO maintained its “open-door” policy but Ukraine’s path to membership remained stalled due to lack of consensus among NATO members, ongoing conflict in eastern Ukraine, and concerns about corruption and democratic reforms.
- The U.S. under President Biden supported Ukraine’s sovereignty but emphasized that membership was not imminent, stating Ukraine needed to address corruption and meet NATO standards.
Russia’s Position
Russia strongly opposed Ukraine’s potential NATO membership, viewing it as a threat to its security. In December 2021, Russia issued demands for legally binding guarantees against NATO’s eastward expansion, specifically barring Ukraine from joining.
Diplomatic Efforts
- A virtual summit between Putin and Biden took place on December 7, 2021, where Putin pressed for denying Ukraine’s NATO bid.
- Diplomatic exchanges continued, with a meeting planned between U.S. Secretary of State Blinken and Russian Foreign Minister Lavrov for February 24, 2022, which was canceled when Russia invaded that day.
Recent Developments
- In September 2022, following Russia’s attempted annexations of Ukrainian territory, Ukraine formally submitted an application to become a NATO member.
- At the 2023 Vilnius summit, NATO waived the need for a Membership Action Plan for Ukraine.
- The 2024 Washington Summit reaffirmed that Ukraine’s future is in NATO, but did not extend a formal invitation. NATO described Ukraine’s path to membership as “irreversible” but stated that an invitation would be extended when “Allies agree and conditions are met.”
- As of February 2025, NATO continues to support Ukraine’s progress on interoperability and reforms, but a specific timeline for membership has not been set.
- Recent statements from U.S. Secretary of Defense Pete Hegseth suggest that Ukraine joining NATO is currently seen as unrealistic.
- On February 23, 2025, President Volodymir Zelenskyy indicated a willingness to “give up” his presidency in exchange for peace, highlighting the ongoing complexities of the situation.
