Europe today is a continent attempting to learn to live without illusions. Indeed, the entire world finds itself at a crossroads of significant changes, transformations not limited solely to the economy or social structures but extending profoundly into global security. Strategic priorities are shifting, long-standing alliances are losing stability, and trust in international institutions is rapidly declining. Amid this turbulent reality, a logical yet unconventional question arises: Is a new architecture for European security possible outside the NATO framework?
After decades of stability underpinned by the American "nuclear umbrella" and the global responsibility of the United States, Europe faces an alarming prospect, especially considering the isolationist statements of the 47th U.S. President, Donald Trump. Thus, who will now guarantee peace on the Old Continent?
European leaders are gradually reconsidering their roles in this issue. Germany is increasing its defense budget, the UK is intensifying military cooperation with allies, and France is increasingly vocal about strategic sovereignty. However, the most unexpected—and potentially most powerful—format could become the geopolitical triangle "Ukraine–UK–France."
This is not utopian. Such an alliance has valid grounds to emerge from current challenges if the UK and France assume a new level of responsibility for European security. Its potential is clear: Ukraine has unique modern war experience; the UK possesses a nuclear arsenal, diplomatic flexibility, and global connections; France holds independent deterrence forces outside NATO and significant influence within the EU and UN. Together, they represent more than just symbolism—they provide a tangible platform for establishing a new security equilibrium on the continent.
Germany was deliberately "ignored" in this configuration for several reasons. Let's begin with the advantages of including Germany in such an alliance:
- Additional influence within the EU (potential leader of European strategic autonomy).
- Economic strength as a source of long-term security assurance.
- Active participation in military-industrial cooperation projects (especially with France).
However, there are substantial "buts" complicating this scenario:
Geopolitical Caution. Germany traditionally acts cautiously in security matters. Its historical context and political culture predispose it toward multilateralism (NATO, EU, UN), rather than new "exclusive" blocs.
Internal Elite Divisions. In Berlin, there is a certain caution toward France regarding strategic autonomy and an ambivalent attitude toward the UK following Brexit. Thus, a triangle involving London and Paris without Berlin could prove simpler politically.
Weak Military Culture. Despite budget increases, the Bundeswehr remains in transformation and struggles with efficiency issues. Including Germany might weaken the operational capability of the alliance, at least in the short term.
Thus, Germany undoubtedly holds potential for participation in a new European security system and could become a strategic partner for the geopolitical triangle "Ukraine–UK–France."
A New Need – A New Geopolitical Geometry
Since Russia's full-scale aggression against Ukraine in 2022, the global security architecture has faced severe challenges. Traditional institutions such as the UN, OSCE, and even NATO proved unable to swiftly respond to emerging threats. This has increased confidence in regional alliances capable of faster adaptation.
One such new format is the AUKUS alliance, created in 2021 between Australia, the UK, and the US. Its purpose is to enhance defense capabilities in the Indo-Pacific region, notably through transferring nuclear submarine technology to Australia. However, implementation in 2025 faces significant challenges. The introduction of US tariffs on steel and aluminum imports, accounting for 35% of total imports from allies like the UK and Canada, could delay submarine production. Moreover, strategic concerns arise regarding the value of transferring submarines to Australia, potentially reducing US deterrence capabilities against China.
Another example is the Bucharest Nine (B9), a cooperation format of nine Central and Eastern European countries established in 2015 in response to Russia's aggressive actions. In June 2024, B9 leaders met in Riga to discuss NATO summit preparations and enhanced support for Ukraine.
The Lublin Triangle, founded in 2020 by Ukraine, Poland, and Lithuania, also demonstrates effective regional cooperation. In January 2024, the leaders of these countries met in Kyiv to discuss increasing NATO's presence on the eastern flank.
These examples highlight the effectiveness of flexible regional alliances in security matters. In this context, the idea of creating a new geopolitical triangle "Ukraine–UK–France" emerges. Such an alliance could unite Ukraine’s combat experience, the UK's strategic resolve, and France's nuclear capabilities, thus enabling a new European security architecture capable of effectively addressing contemporary challenges.
Ukraine–UK: Proven Allies
In times when global security structures face severe challenges, the UK emerges as one of Ukraine's most reliable partners. Since the beginning of Russia’s full-scale aggression in 2022, London has consistently and decisively supported Kyiv on both military and diplomatic fronts.
The UK was among the first countries to provide Ukraine with modern weapons, including NLAW anti-tank systems crucial in halting Russian armored columns at the initial war stages. In 2024, Britain delivered Storm Shadow cruise missiles, significantly boosting Ukraine's capability to strike targets deep behind enemy lines.
In April 2025, the UK provided Ukraine with a second tranche of military loans worth £752 million ($990 million), part of an overall £2.26 billion aid package. These funds are intended for air defense systems, artillery, and equipment maintenance.
Moreover, the UK actively trains Ukrainian troops under Operation Interflex, with over 30,000 personnel trained since 2022. This training encompasses infantry tactics, engineering, medicine, and logistics.
Politically, the UK firmly backs Ukraine, exemplified by the January 2024 security cooperation agreement between Prime Minister Rishi Sunak and President Volodymyr Zelenskyy, promising £2.5 billion in military aid.
In 2025, Britain plans to provide Ukraine with £4.5 billion in assistance, underscoring long-term commitment.
Overall, UK–Ukraine cooperation exemplifies effective bilateral security collaboration. London not only delivers substantial military and financial support but also actively engages in strategic planning and training of Ukrainian forces. Within the context of a new geopolitical triangle, the UK component emerges as a proven and reliable ally ready for deeper integration and joint response to contemporary security challenges.
Ukraine–France: Evolution from Caution to Support
French policy toward Ukraine has never been simple or straightforward. Unlike the UK, which took a clear and active stance from the very first days of Russia’s full-scale aggression, France long remained in the shadows of diplomatic courtesies and strategic restraint. But over the course of three years of war, Paris has undergone its own transformation—from measured caution to tangible military and political support. This turning point may position France as a key player in a potential new geopolitical triangle.
France made its first significant military gesture in 2022 by supplying Ukraine with CAESAR self-propelled artillery systems. These highly mobile and precise weapons became an important component of Ukraine’s artillery advantage across several directions. Later, France delivered SCALP missiles—its analogue to the UK’s Storm Shadow—which can strike targets over 250 km away.
At the same time, France increased its supply of air defense systems in 2024–2025. Ukraine received modernized air defenses, including SAMP/T systems (in cooperation with Italy), as well as short-range systems. In April 2025, France confirmed plans to increase ammunition and weapons deliveries as part of a joint European fund aimed at supporting Ukraine.
The President of the Fifth Republic, whose style often oscillates between strategic depth and unpredictable rhetoric, made several bold statements that forced many to reconsider France’s image as a “cautious” player.
In February 2024, he publicly did not rule out the deployment of foreign troops on Ukrainian territory “if the situation demands it.” In April 2025, he reiterated this stance, stating that the West “cannot allow Russia to win” and that “all options must remain on the table.”
These declarations marked a shift in the perception of France—not just as a European democracy with a powerful army, but as a nuclear state willing to participate in reshaping the regional balance of power.
Strategic Autonomy and Ukraine’s Place in Europe
The concept of “strategic autonomy” has long been a favorite of President Macron. It implies that Europe should have the capability to defend itself without depending on the United States. In the past, this was seen as a diplomatic message to Brussels. But the war in Ukraine has made this idea more concrete—revealing that even a united Europe is not yet prepared to defend itself without American help.
In this context, Ukraine is becoming not a beneficiary of European security but a co-creator of it. Kyiv is no longer just the “eastern front” but the center of a joint struggle for freedom. France increasingly acknowledges this reality, as evidenced by regular visits of French ministers to Kyiv, defense agreements, and French business involvement in rebuilding Ukraine’s infrastructure.
France and the UK—two old empires that for centuries competed for influence in Europe and the world, from the Hundred Years’ War to 19th-century colonial rivalry—are now facing shared challenges. The 21st century, especially the war in Ukraine, has redrawn the map. Today, Paris and London increasingly understand that common threats—from Russia to uncertain transatlantic relations—demand new formats of cooperation.
The UK’s departure from the European Union in 2020 created a noticeable gap in Europe’s political landscape. On one hand, London freed itself from the limitations of Brussels bureaucracy. On the other hand, it lost mechanisms for direct influence over European policy. That’s why Britain began seeking new ways to assert its status on the continent—and security initiatives became central.
In 2022, the European Political Community (EPC) was created—a platform initiated by Macron and supported by the UK. It became a symbol that even outside the EU, London and Paris can shape common security and geopolitical strategies.
France and the UK are the only nuclear powers in Europe. Both have aircraft carriers, strategic forces, and high-tech armies. And despite their historical rivalry, both countries have long recognized: survival in a changing world requires partnership.
Back in 2010, France and the UK signed the Lancaster House Treaty on strategic defense cooperation. It provided for joint military exercises, the development of defense technologies, and even the creation of joint expeditionary forces. Since the start of the full-scale war in Ukraine, this cooperation has only intensified. In 2024, both countries agreed to coordinate long-range weapons supplies to Ukraine and expanded joint projects in the European defense industry.
It’s also worth noting the work of British BAE Systems and French Thales, which, along with German partners, are developing next-generation air defense systems and strike platforms. This is no longer just business—it’s the creation of a shared security environment.
The Need for Strategic Partnership Without Washington??
Although the United States remains the most powerful Western ally, a new American political wave is forcing Europe to reconsider its own security autonomy. Here, France and the UK are natural leaders.
Both countries possess resources, experience, defense industries, and the geopolitical will to act. Their shared direction could become the foundation for forming new alliances, particularly those elevating the role of countries like Ukraine—one that has proven its ability to resist aggression and is seeking partnership, not charity.
While Paris and London still have differences—such as divergent views on the EU or migration policy—the shared threat landscape increasingly outweighs historical disagreements. Ukraine could become the "common denominator" that transforms Franco-British interaction into a strategic alliance for the future.
The political return of Donald Trump to the global stage is not merely a domestic U.S. matter. For Europe, it is a factor of strategic uncertainty that is already reshaping the security landscape. Trump is not a conventional Republican—his views on NATO, transatlantic unity, and America's global role reflect a doctrine of cold calculation rather than value-based partnership.
Back in February 2024, Trump shook the international community with his statement: "If NATO countries don’t pay, I won’t protect them. At best, I’ll wish them luck."
Though politically motivated, these words resonated in European capitals. It wasn’t the first time. During his presidency from 2017 to 2021, Trump repeatedly undermined NATO's relevance and criticized "wasting resources on other people’s wars."
Now, as he vies for the White House again, his rhetoric is even more blunt. Given growing conservative support in the U.S., Europe must brace for the worst-case scenario: American isolationism could become official policy by 2025.
Trump’s statements did not remain headlines alone—they catalyzed a rethinking of defense policies across Europe. Germany, long reluctant to discuss military matters, announced a defense budget increase to over 2% of GDP, the creation of new brigades, and the revival of heavy equipment production.
Macron declared that "Europe must be capable of defending itself independently." Meanwhile, in the UK, there’s growing debate about restoring mandatory military service and boosting defense autonomy in post-NATO scenarios.
At a time when Europe’s main security guarantor—the U.S.—may exit the game or significantly reduce its involvement, Europe must develop internal mechanisms of protection. In this context, a new geopolitical triangle between Ukraine, the UK, and France emerges not as an alternative to NATO but as its European insurance platform.
France is the EU's only nuclear-armed country. The UK is a global military power with a legacy of force projection. Ukraine holds the most extensive modern combat experience in Europe, moral authority, and an army that contains the "second strongest military in the world."
Together, these three countries can not only complement one another, but also set the tone for a new European security architecture. And in times when Washington may no longer be the one to "always come to the rescue," we need those who will always remain.
Challenges and Risks
The idea of a geopolitical triangle between Ukraine, the UK, and France appears promising, but behind its justification lie not only opportunities but also a range of serious challenges. Despite its strategic logic, forming such an alliance confronts a number of obstacles that could complicate its formalization.
The biggest hurdle is the absence of unified political will among key participants. The UK, post-Brexit, seeks to reaffirm its global role. However, its political trajectory—often unpredictable—complicates the formation of stable long-term strategies. Additionally, London has not yet defined its future relationship model with the EU, making it harder to shape a clear stance toward cooperation with Ukraine.
France, for its part, has pursued a strategy of "EU strategic autonomy" for several years. While this could theoretically enhance its role in any European alliance, France's interests often diverge from those of the UK. France is also politically diverse—Macron’s relations with other domestic forces vary, and internal disagreements on foreign policy could hinder support for this alliance.
Another enduring factor is the historic rivalry between France and the UK. Though the two now work jointly on global issues like counterterrorism and European defense, longstanding frictions could resurface—especially when it comes to sharing leadership in new alliances.
A critical issue is resources. Despite Ukraine’s military strength and battlefield experience, it remains a nation at war, facing immense economic and social pressures. Even if the political will exists, Ukraine’s capacity to fully participate in ambitious alliances is limited by its domestic needs—reconstruction, economic stabilization, and development.
One of the most important challenges is the lack of formalization. While regional alliances like the Bucharest Nine or Lublin Triangle mostly remain declarative, there are doubts about whether the "Ukraine–UK–France" triangle can evolve into a true intergovernmental alliance with binding legal commitments. Without this formal basis, the concept risks remaining symbolic, incapable of anchoring a stable European security strategy.
This may be the most critical and complex challenge. The triangle appears to suffer from a trust deficit—not only between Ukraine and its Western partners but also between the UK and France themselves. The rise of populist movements across Europe has made foreign policy increasingly dependent on domestic electoral cycles. Political changes in any of these three countries could derail shared strategies.
Is Now the Time for Bold New Alliances?
In conclusion, ongoing global and regional changes are pushing Europe to reconsider its security architecture. Many traditional models have proven insufficient against modern threats. With strategic uncertainty growing and the U.S. potentially stepping back from European affairs, new alliances are needed to ensure stability on the continent.
The idea of a "Ukraine–UK–France" alliance is becoming increasingly relevant. This partnership holds enormous potential due to the unique strengths of each country: Ukraine’s combat experience and military capability, the UK’s global ambition and power projection, and France’s capacity to drive European strategic autonomy.
Even if this triangle doesn’t fully replace NATO, it can serve as a vital pillar of Europe’s new security architecture. Its key advantage lies in elevating Ukraine from a recipient of aid to a strategic partner actively defining its place in both European and global contexts.
To succeed, however, this vision must overcome numerous obstacles: political differences, lack of legal structure, and Ukraine’s resource limitations. But if implemented, the triangle could become a significant step toward a new security reality for Europe. Given all circumstances, the "Ukraine–UK–France" alliance could be a foundational element in strengthening European security—even in a future where U.S. involvement wanes.
Today, as global security institutions struggle to respond to fast-changing conditions, Europe must move beyond traditional models and seek new modes of cooperation. This requires bold steps and a readiness to adopt flexible yet effective strategies. Ukraine, the UK, and France together hold the potential to become the new pillars of European security—guaranteeing peace and stability on the continent.
