• NATO has signaled stronger support for Ukraine's ability to strike deeper into Russian territory, according to Finland's President Alexander Stubb.
  • The shift reflects growing alliance unity amid renewed Russian offensives and Ukraine's urgent need for expanded military capabilities.
  • Finland, a recent NATO member, is playing an increasingly active role in shaping the alliance's posture.

Finland’s President Alexander Stubb said Thursday that NATO member states have broadly endorsed Ukraine’s calls to loosen restrictions on using Western-supplied weapons for strikes inside Russia. Speaking after a closed-door session with alliance leaders, Stubb noted a “clear consensus” that Ukraine must be able to defend itself effectively, including by targeting Russian military infrastructure beyond its border.

“There is a growing understanding that Ukraine’s ability to hit legitimate military targets on Russian soil is not an escalation, but a necessary part of self-defense,” Stubb said in a statement to reporters in Helsinki. He added that several NATO countries had privately signaled they would support removing previous caveats on long-range systems.

The development marks a notable shift in NATO’s stance, which had previously discouraged deep strikes for fear of provoking a wider conflict. However, recent Russian missile barrages against Ukrainian energy grids and civilian areas have hardened allied positions. According to people familiar with the matter, the U.S. and U.K. have been discussing revisions to their own guidance, though no formal announcement has been made.

Finland, which joined NATO in April 2023 after decades of non-alignment, has emerged as a vocal advocate for a more aggressive approach. Stubb’s comments come as Ukraine’s military struggles to hold back Russian advances in the east, where Moscow has achieved marginal gains in recent weeks. Kyiv has repeatedly appealed for longer-range missiles and permission to use them against Russian supply hubs.

The new backing could accelerate delivery of advanced systems, such as the UK’s Storm Shadow cruise missiles or U.S.-made ATACMS, which have previously been restricted to targets within occupied Ukrainian territory. “This would be a game-changer in terms of disrupting Russia’s rear logistics,” said a senior European defense official who spoke on condition of anonymity to discuss sensitive planning.

Cryptic wording in a recent NATO communiqué hinted at the shift. The document, obtained by Bloomberg, states that allies “remain committed to supporting Ukraine’s inherent right to self-defense, including through the provision of capabilities that can reach beyond immediate front lines.” It stops short of explicitly endorsing cross-border strikes, but diplomats say the language was carefully calibrated to signal flexibility.

In Russia, Foreign Ministry spokeswoman Maria Zakharova warned that any escalation would “lead to irreversible consequences for European security.” The Kremlin has long drawn red lines against NATO weapons hitting Russian soil, though previous threats have not materialized into direct confrontation.

Stubb’s remarks also underscore Finland’s evolving role within the alliance. Once a cautious neutral, the Nordic country now hosts NATO troops and has boosted its defense spending to 2.6% of GDP. This week, it announced a new €200 million aid package for Ukraine, including artillery shells and counter-drone systems.

“Finland’s voice carries weight because we understand the Russian threat firsthand,” said Mika Aaltola, director of the Finnish Institute of International Affairs. “Stubb is pushing for a posture that balances deterrence with measured risk."

The immediate impact on Ukraine’s battlefield options remains uncertain. Even with NATO’s blessing, any new strike permissions would require individual member states to adjust their export controls. But the political momentum is clear.

As Stubb put it: “We have moved from debating whether to support Ukraine to debating how to support Ukraine more effectively.”
