United States Secretary of State Marco Rubio announced on October 6, 2026, that Ukraine’s membership in the North Atlantic Treaty Organization (NATO), a political and military alliance of 32 member states, is “not on the table” at present. Rubio, who also serves as the US National Security Advisor, stated that the United States is “simply focused” on bringing an end to the ongoing conflict in Ukraine.
Ukraine is a partner country to NATO, but it is not a member state. NATO allies, during their 2026 Ankara summit, committed to providing €70 billion in military equipment, aid, and training to Ukraine for 2026, with a pledge to maintain this level of assistance into 2027.
The relationship between NATO and Ukraine formally began in 1991 when Ukraine gained independence and joined the North Atlantic Cooperation Council (NACC). A significant step was taken in 1997 with the establishment of the NATO-Ukraine Commission and the signing of the Charter on a Distinctive Partnership, which laid the formal groundwork for their cooperation.
Despite this, Ukraine’s path to full membership has been complex. At the 2008 Bucharest summit, NATO declined to offer Ukraine a Membership Action Plan (MAP) but affirmed that Ukraine would eventually join the alliance. Russia’s aggression, starting with the annexation of Crimea and support for separatists in Donbas in February 2014, intensified Ukraine’s pursuit of NATO membership.
The conflict escalated dramatically with Russia’s full-scale invasion of Ukraine on February 24, 2022. In response, Ukraine formally applied for NATO membership in September 2022. The 2023 Vilnius summit marked a change in approach, as NATO allies decided to exempt Ukraine from the MAP requirement, streamlining its membership path from a two-step to a single-step process.
However, US President Donald Trump, in February and March 2025, had previously suggested that Ukraine should “forget” about joining NATO. Rubio’s recent comments reiterate the US focus on conflict resolution.
The United States’ immediate focus remains on ending the conflict in Ukraine and playing a constructive role in peace negotiations. While NATO allies continue their substantial support, any decision regarding Ukraine’s full NATO membership requires unanimous agreement among all allied nations and the fulfillment of unspecified conditions.
Rubio observed that current trends do not indicate an early resolution to the conflict. This contrasts with a statement by NATO Secretary General Mark Rutte on June 2, 2026, who confirmed that Ukraine’s NATO membership was indeed on the agenda. The precise conditions for Ukraine’s membership, beyond general agreement and fulfillment of terms, remain unspecified, and the timeline for the conflict’s potential end is uncertain.
