Sweden argues Ukraine's NATO and EU entry would strengthen, not strain, both blocs

Sweden's foreign minister has made an explicit case that Ukraine's accession to both the European Union and NATO would strengthen the existing members of both institutions, framing Ukrainian integration not as a burden on Western alliances but as a net gain for European security.

Maria Malmer Stenergard, speaking at a press conference in Kyiv following a Coalition of the Willing summit on 24 August 2026, said that EU membership would offer Ukraine its most reliable security guarantee, while NATO membership would enhance the alliance's collective deterrence against Russia. The dual argument, delivered in the Ukrainian capital rather than from Stockholm or Brussels, was designed to counter the implicit assumption in several Western capitals that Ukrainian accession to either institution primarily benefits Kyiv at the expense of existing members.

Ukraine as security provider, not dependent ally

The centrepiece of Stenergard's argument was the claim that Ukraine has, over four and a half years of full-scale war, transformed from a country seeking Western protection into one that exports security knowledge to others. "We have seen Ukraine become a security provider for all of us," she told reporters.

She pointed to Ukraine's willingness to share its combat experience with Gulf states during the armed conflict in Iran, describing it as evidence that Kyiv's accumulated knowledge of modern warfare has relevance well beyond its own borders. The reference to Iran was striking: it linked the European war to a different theatre entirely, suggesting that Ukrainian expertise in drone warfare, electronic warfare and integrated air defence has become a commodity that Western allies and partners actively seek.

Her broader point was more provocative still. "Now, two countries in our region have the most advanced knowledge of how to wage war," she said. "And one of them is our friend. And we really need Ukraine on our side, because Ukraine provides security not only for itself but for all of Europe." The other country, left unstated, was plainly Russia. The implication is that the military knowledge accumulated through sustained high-intensity combat is now concentrated in Moscow and Kyiv, and that Europe's interest lies in ensuring the side that possesses it remains inside the Western institutional framework rather than outside it.

Two tracks, one logic

Stenergard paired her argument for NATO membership with a separate claim about EU accession, calling it "Ukraine's best security guarantee." The two arguments are connected but distinct. NATO membership provides a military deterrent through Article 5's collective defence commitment. EU membership, by contrast, provides economic integration, political alignment and the long-term institutional pull that has historically anchored post-conflict recoveries in Eastern Europe, from the Baltic states to Poland.

Linking the two tracks is not accidental. For countries that remain wary of extending NATO's mutual defence clause to a country still engaged in active combat with Russia, the EU track offers a less immediately consequential path. But Stenergard was not presenting EU membership as a consolation prize. She presented it as the deeper guarantee: the one that reshapes a country's economic structure, governance and legal framework over decades, making military conflict with a neighbour far less likely in the first place. The EU enlargement process has historically served exactly this function for post-communist states, binding them to Western norms and markets.

The NATO argument, by contrast, is about deterrence in the narrower sense: making clear to Moscow that an attack on Ukraine would trigger a response from all 32 current members. Stenergard said she was "convinced" that Ukraine's membership "would mean greater security for the rest of the NATO countries and significant deterrence of Russia." That is a direct challenge to the position held by several alliance members, including the United States and Germany, which have repeatedly stated that Ukraine cannot join NATO while the war is ongoing and that the alliance must avoid steps that could draw it into direct confrontation with Russia.

Sweden's particular credibility

Sweden's foreign minister is not the most obvious voice to be making this case, but she is a credible one. Sweden abandoned more than two centuries of military non-alignment to join NATO in March 2024, a decision forced by Russia's full-scale invasion of Ukraine and the consequent reshaping of the Baltic security environment. Stockholm knows what it means to reconsider long-held strategic assumptions in response to Russian aggression, and it has made the argument that institutional membership, however belated, is preferable to unprotected neutrality.

Sweden has also been among the more generous European donors of military assistance to Ukraine, relative to the size of its economy. The talks between Ukrainian Navy Commander Vice Admiral Oleksii Neizhpapa and his Swedish counterpart, reported alongside Stenergard's press conference, suggest that Stockholm's military support continues to deepen, particularly in naval capabilities relevant to the Black Sea and Baltic theatres. NATO's relationship with Ukraine has expanded through various partnership frameworks, but full membership remains the unresolved question.

The Coalition of the Willing format

Stenergard's remarks were delivered at a press conference following a Coalition of the Willing summit held in Kyiv. The format, which brings together countries prepared to commit to specific forms of support for Ukraine outside the constraints of broader institutional processes, has become a recurring feature of the diplomatic landscape. It allows participating states to coordinate military, financial and reconstruction assistance without requiring consensus among all EU or NATO members.

The choice of Kyiv as the venue matters. Holding the summit in the Ukrainian capital, rather than in Brussels, Warsaw or Stockholm, is both a signal of political solidarity and a practical reminder that decisions about Ukraine's future are being made in a country still under bombardment. It also gives participating ministers a direct line of sight to the conditions under which Ukrainian forces are operating, something that can sharpen the rhetoric when they return to their own capitals.

What the sceptics will make of this

Stenergard's argument is coherent but unlikely to shift the positions of the alliance's larger members quickly. Washington's concern, shared in different measure by Berlin and Paris, is that extending Article 5 to Ukraine before a stable ceasefire or peace settlement is in place would commit the alliance to direct military engagement with Russia. The counter-argument, which Stenergard articulated, is that the uncertainty about Ukraine's eventual NATO status is itself a source of instability: it tells Moscow that there is a pathway to preventing Ukraine's accession through continued military pressure.

There is also a domestic politics problem in several European countries. Public support for military aid to Ukraine remains broad but has softened in places, and the argument that Ukraine's accession would strengthen alliance security requires voters to accept that a country with 3,000 kilometres of active frontline could become a net contributor to collective defence rather than a liability. Stenergard's framing, which emphasises Ukraine's accumulated combat expertise, is designed to bridge that gap. Whether it succeeds depends on whether other European leaders adopt the same language.

The Iran reference and what it signals

Perhaps the most unexpected element of Stenergard's remarks was her reference to Ukraine sharing military experience with Gulf countries during the armed conflict in Iran. The detail was offered without elaboration, but it does specific political work in the argument. It positions Ukraine not merely as a recipient of Western assistance but as a country whose combat knowledge is sought by states outside the Euro-Atlantic framework. That reframes the relationship: if Gulf states are learning from Ukraine, the logic goes, then NATO members should want Ukraine inside the alliance rather than alongside it.

The reference also serves a second purpose. By linking Ukraine's expertise to the Iran conflict, Stenergard connected the European security crisis to broader Western strategic concerns in the Middle East, implicitly arguing that Ukraine's value as an ally extends beyond the continental theatre. For a Swedish government seeking to maintain domestic and international support for its Ukraine policy, broadening the frame of reference beyond Europe's borders is a calculated move.

Where the accession debates actually stand

Ukraine's EU accession negotiations formally opened in June 2024, and the process has moved faster than many expected, though still more slowly than Kyiv would like. The European Commission has praised Ukraine's legislative and institutional reforms in several chapters, but the negotiating process involves 35 acquis chapters, each requiring alignment with EU law, and no serious observer expects full membership before the end of the decade at the earliest. The question of agricultural competition, reconstruction costs and rule-of-law standards remains unresolved, and several current member states have made clear that they expect a long process, not an accelerated one.

NATO membership is further away still. The alliance's 2022 Madrid summit declared that Ukraine's future lay in NATO, and the 2023 Vilnius summit removed the requirement for a Membership Action Plan, but no timeline has been set. The alliance's formal position remains that Ukraine will join when conditions permit, a formulation that allows member states to defer the question indefinitely. The Vilnius communiqué established a NATO-Ukraine Council but stopped short of the invitation Kyiv had sought.
