Ukraine's NATO Membership: A Strategic Vision or Wishful Thinking Fraught with Risks?

By Lt Gen (ret) Konstantinos Loukopoulos

Finnish President Alexander Stubb declared once again on Saturday that Ukraine will eventually become a member of NATO. On the same day, Polish Deputy Prime Minister and Foreign Minister Radosław Sikorski expressed a similar view, despite the current tensions in Polish-Ukrainian relations. At a time when fighting has intensified across the front line and Ukrainian long-range strikes are reaching Moscow, such statements appear intended to send a message of solidarity to Kyiv and reaffirm that Russia cannot dictate the security choices of a sovereign state. To a certain extent, this is understandable.

But is this a serious strategic assessment, or merely a superficial political declaration that creates dangerous illusions and unrealistic expectations? I would argue, without hesitation, that NATO, as a collective institution, has not been entirely candid with Ukraine regarding its prospects for membership.

A Brief Historical Perspective

This lack of candor dates back to April 2008. At NATO's Bucharest Summit, despite strong pressure from U.S. President George W. Bush, Ukraine—and Georgia—were not granted a Membership Action Plan (MAP), the formal pathway toward accession. Consensus among the Allies could not be achieved, largely because Germany, France, and several other member states foresaw serious strategic complications with Russia.

Since then, NATO has repeatedly declared that its "door remains open" to Ukraine, yet Kyiv has never been granted MAP status. The rhetoric of eventual membership continued for years, even during the diplomatic exchanges between Russia and the West immediately preceding the 2022 invasion.

It is worth recalling that MAP does not constitute membership. Rather, it represents, on the one hand, a commitment by the candidate country to undertake the political and military reforms required for accession and, on the other, a commitment by the Alliance to keep NATO's door open in accordance with Article 10 of the North Atlantic Treaty.

The Promise Versus the Reality

The debate over Ukraine's NATO membership continues to dominate discussions within parts of the European political establishment, particularly among the Baltic states and Poland, despite the fact that even under President Biden, the United States, Germany, France, and several other allies refrained from endorsing a concrete accession timetable.

The reason is obvious. Admitting a country that is actively at war with a nuclear power could draw NATO directly into a military confrontation with Russia.

Even after the war eventually ends, fundamental questions will remain. Under what conditions could NATO admit a country with unresolved territorial disputes and without a comprehensive peace agreement? More importantly, how could such an outcome be reconciled with one of Moscow's explicitly declared war aims: preventing Ukraine from joining NATO?

The Negotiation Deadlock

This is where the central contradiction lies.

Russia has made it abundantly clear that it considers Ukraine's accession to NATO an existential threat to its national security. One may agree or disagree with that position, but it cannot simply be ignored if the objective is a negotiated settlement.

If one of the principal issues invoked by one side is declared non-negotiable from the outset, what meaningful room remains for diplomacy?

The repeated assertion that Ukraine's NATO membership is "inevitable" may sound supportive of Ukraine. In reality, however, it narrows—if not eliminates—the space for compromise. Rather than creating conditions for dialogue, it entrenches incompatible positions and makes a political settlement even more difficult.

This explains why every serious peace proposal—including those reportedly discussed within former President Donald Trump's framework—rules out NATO membership while offering Ukraine robust alternative security guarantees.

A Different European Strategy

If the genuine objective is to protect Ukraine rather than indefinitely prolong the war, then European diplomacy should focus on shaping a new pan-European security architecture through negotiations with Moscow.

Europe's major crises have never been resolved solely on the battlefield. They have also been settled at the negotiating table, when adversaries accepted a new security equilibrium. The question is whether today's political leadership possesses the will to pursue such an approach.

Does NATO Membership Require Russia's Defeat?

An even more difficult question must be addressed.

What would Ukraine's NATO membership actually require in practice?

Since Russia has unequivocally stated that it will never accept such an outcome, implementing this policy would appear to require either a decisive military defeat of Russia or such a profound weakening of the Russian state that it could no longer effectively resist.

Is it truly realistic to build European strategy on the assumption that a nuclear superpower will collapse—or quietly acquiesce—while already controlling roughly 21–22 percent of Ukrainian territory?

If the answer is no, then repeated promises of NATO membership risk becoming little more than political slogans satisfying an uncompromising anti-Russian posture rather than representing a viable strategic policy.

Is NATO a Defensive Alliance or a Political Prize?

This debate also raises fundamental questions about NATO itself.

The Alliance was founded as a collective defense organization. It was not designed as an institution whose enlargement depends upon the strategic defeat of another great power.

This does not mean that Ukraine has no right to seek NATO membership, nor that NATO members have no right to consider future enlargement. It does mean, however, that strategic decisions should be judged by their likely consequences rather than by their political symbolism.

It is also worth noting that President Volodymyr Zelensky himself has publicly acknowledged that Ukraine cannot join NATO under the current circumstances.

Conclusion

The essential question is not whether Ukraine deserves NATO membership.

The real question is whether repeated promises of accession, without a credible path toward implementation, increase the prospects for peace—or instead transform the conflict into an open-ended war with no clear exit.

History teaches us that foreign policy should ultimately be judged not by its intentions but by its results. If a policy, however morally appealing it may sound, makes peace less likely, then perhaps the time has come for Europe to move beyond declaratory politics and return to strategic realism.

Wars end either through the decisive victory of one side over the other, allowing the victor to impose its will, or through diplomacy that succeeds in bridging what military force alone cannot resolve.
