The Kremlin has elevated Ukraine’s refusal to join NATO to the status of a non-negotiable pillar in any future talks to end the war, underscoring how central the issue remains to Moscow’s diplomatic calculus. The position was articulated by Kremlin spokesman Dmitry Peskov, The WP Times, citing Russia’s state-run news agency TASS.
Responding to questions about who Moscow expects to provide a legally binding document confirming Ukraine’s non-membership in NATO, Peskov said the matter lies at the very core of a prospective peace process. He stressed that this requirement is not secondary but fundamental to Russia’s negotiating position.
“This is precisely why this issue requires separate and particularly careful discussion alongside the main elements of negotiations,” Peskov said. “That is the nature of the negotiating process, which, I want to emphasise once again, we do not intend to conduct in a megaphone format.”
NATO membership and diplomatic context
Ukraine had hoped to secure a formal invitation to join NATO at the Alliance’s summit in Washington in July 2024. No such invitation was extended, despite strong public support from Kyiv and a number of NATO member states. The absence of a clear invitation has since fuelled renewed debate over Ukraine’s long-term security architecture.
Discussion of Ukraine’s possible NATO membership intensified further after the United States presented a peace framework aimed at bringing the war to an end. According to media reports, potential arrangements between NATO member states and Russia could result in Ukraine being formally denied a path to Alliance membership.
One of the most controversial elements of earlier US proposals was reportedly the suggestion that Ukraine would need to officially renounce its aspiration to join NATO. This condition was described by sources as one of the most problematic aspects of the initial peace outline, given Kyiv’s long-standing strategic goal of integration with Euro-Atlantic institutions.
US President Donald Trump has stated that the understanding that Ukraine would not become a NATO member had taken shape long before Russian President Vladimir Putin publicly articulated this position. His remarks suggested that the issue had been informally acknowledged in diplomatic circles well before becoming a central talking point in public negotiations.
At the same time, media reports indicate that the US administration is prepared to offer Ukraine legally binding security guarantees, potentially modelled on Article 5 of the NATO Treaty, which enshrines the principle of collective defence. Such guarantees, if implemented, would represent a significant shift in Washington’s approach to Ukraine’s security, even in the absence of formal NATO membership.
