Europe Eyes Nuclear Deterrent as U.S. Commitment Wavers

Rising global tensions and shifting U.S. foreign policy are prompting a serious reconsideration of Europe’s nuclear defense strategy.

The idea of a European nuclear deterrent, once relegated to the fringes of geopolitical discourse, is gaining traction as the United States signals a potential recalibration of its security commitments on the continent. This shift has ignited a debate about Europe’s ability to secure itself in an increasingly volatile world.

Earlier this month, Polish Prime Minister Donald Tusk addressed his nation’s parliament, stating, Poland must pursue the most advanced capabilities, including nuclear and modern unconventional weapons. This is a serious race — a race for security,not for war. Tusk’s words, delivered against the backdrop of a potential U.S. pullback, suggest a dramatic departure from decades of European non-proliferation policy.

The situation is further complex by Russia’s ongoing military aggression in Ukraine and China’s rapidly expanding nuclear arsenal. Russia,possessing the world’s largest stockpile of nuclear warheads,has repeatedly brandished the threat of nuclear force to deter NATO and the EU from direct military intervention in the conflict. This leaves Europe facing a complex dilemma: how to maintain a credible nuclear deterrent and whether additional nations will seek nuclear capabilities.

While several European countries possess elements necessary for developing autonomous nuclear weapons,experts suggest the likelihood of widespread proliferation in Europe remains low.However, the question is no longer entirely academic.

Building from the Ground Up: A Herculean Task

According to Fabian Rene Hoffmann, a research fellow at the Oslo Nuclear Project, even for European NATO members eager to independently develop nuclear weapons, significant hurdles exist. He stated, The major issue European countries are facing is that they either don’t deploy the civilian nuclear infrastructure to launch a nuclear weapons program, or, if they have civilian nuclear infrastructure, that it is highly ‘proliferation-resistant.’

Hoffmann elaborated, For example, Finland and Sweden only have light-water reactors, which are not suitable for the production of weapons-grade plutonium. In addition, neither of those countries have chemical reprocessing plants that are needed for separating wanted from unwanted isotopes in fissile material production. So even if they wanted to launch a nuclear program, they couldn’t do so with thier existing infrastructure, at least in the short-term. That’s the case for all non-nuclear weapon states in Europe with a civilian nuclear programme right now.

Germany presents a unique, though limited, case. While it does not deploy significant civilian nuclear infrastructure anymore, it has a large stockpile of highly-enriched uranium for research purposes.Theoretically, this stockpile could be repurposed under some effort to create weapons-grade fissile material, Hoffmann explained. However, he cautioned that this stockpile woudl only yield enough material for approximately 5 to 15 warheads, insufficient for a robust nuclear deterrent.

The United States faced similar challenges in the early days of its nuclear program. The Manhattan Project, launched during World War II, required a massive investment of resources and scientific expertise to overcome significant technological and logistical obstacles. replicating such an undertaking in present-day europe would be an enormous challenge.

Country	Current Nuclear Capability	Potential obstacles
Poland	None	Lack of nuclear infrastructure,international treaties
Germany	Limited (highly-enriched uranium for research)	small stockpile,political constraints
Sweden	None	Light-water reactors unsuitable for weapons-grade plutonium
Finland	None	Light-water reactors unsuitable for weapons-grade plutonium

Extending the Nuclear umbrella: Options and Obstacles

The United Kingdom and France,the two European nations possessing nuclear arsenals,face critical decisions regarding the future of their deterrents.

The UK’s submarine-based deterrent confronts an uncertain future.Its missile-carrying fleet is aging and needs replacement, and, crucially, its missiles are manufactured and stockpiled in the U.S., making the British deterrent unusually dependent on American involvement. This reliance raises concerns about the long-term viability and independence of the UK’s nuclear forces.

France’s deterrent is larger, more independent from NATO, and includes options beyond submarines. This raises the possibility of “forward-deploying” French nuclear weapons in other European countries. However, as Hoffmann noted, Infrastructure would have to be built up in the hosting states, most notably bunkers. I would also say that forward-deploying French nuclear weapons in Germany wouldn’t really make any difference. If at all, they should be forward-deployed to the frontline states” — that is, Russia-facing countries including Poland.

Poland’s expressed interest in hosting U.S. nuclear warheads underscores the perceived need for enhanced deterrence in Eastern Europe. Such a move would mirror the Cold War strategy of forward-basing nuclear weapons to deter Soviet aggression. though, it would also require navigating complex political and logistical challenges, including potential opposition from within Poland and from Russia.

Out of the Shadows: breaking with decades of norms

following the Cold War’s conclusion and the Warsaw Pact’s dissolution, Poland shed the Soviet nuclear weapons once stationed on its soil. Like most European nations, Poland has as embraced international agreements limiting nuclear weapons proliferation, including the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Comprehensive nuclear-Test-Ban Treaty (CTBT).

If Poland or another European nation were to pursue the progress of nuclear weapons, it would signify a break from a norm that has prevailed in the west for three decades. This action would carry significant consequences for international security and the global non-proliferation regime. The world would be forced to confront the reality of a new nuclear arms race.

The current non-proliferation regime has focused on curbing north Korea’s nuclear program,preventing weapons-grade enrichment in Iran,and controlling the flow of uranium,plutonium,and enrichment components. The establishment never expected a European state would develop its own arsenal.

However, the agencies monitoring non-proliferation are adapting to new technologies that could simplify illicit nuclear proliferation. This includes additive manufacturing, or 3D printing, which the US-based Center for Strategic and International Studies warns could create volatile pathways to nuclear capabilities and weapons.

Nuclear Proliferation on the Cheap: A Looming Threat

3D printing could enable aspiring proliferators to bypass scrutiny by domestically printing hard-to-import components. This would allow countries to achieve nuclear capabilities without detection. This poses a significant challenge to the existing non-proliferation framework.

International efforts have focused on making it tough for countries to independently develop nuclear weapons. In a world of 3D printing, AI, and other technologies, the ways countries are stopped from illegally proliferating may have to change.

South Africa’s history serves as a stark reminder of the potential for low-cost proliferation. During the Apartheid era, South Africa developed six nuclear warheads and developed an energy-intensive but low-cost method to enrich uranium, called the Helikon vortex separation process.Some experts worry this process could be used to enrich uranium today.

South Africa is the only country to have developed

Europe’s Nuclear Future: An Interview with Dr. Anya Sharma

archyde News Service speaks with leading nuclear security expert, Dr. Anya Sharma, about the evolving landscape of nuclear deterrence in Europe.

Published March 22, 2025

The Shifting Sands of European Nuclear Strategy

Archyde News: Dr. Sharma, thank you for joining us. Recent developments signal a potential shift in the European approach to nuclear deterrence. How notable is this moment?

Dr. Sharma: It’s a pivotal moment, a real inflection point. The waning certainty of U.S. commitment, coupled with the escalating threats posed by Russia and the rise of China’s nuclear program, have forced Europe to re-evaluate its security paradigm.The debate isn’t just academic anymore; it’s rapidly becoming about concrete security concerns and, possibly, capabilities.

Building a Nuclear Europe? The Practical Challenges

Archyde News: We’ve seen Poland, for example, express interest in bolstering its capabilities. How realistic is it for countries like Poland to develop their own independent nuclear deterrent?

dr. Sharma: That’s where it gets complicated. The path to a nuclear weapon is not easy.Poland, like many European nations, lacks the necessary infrastructure. Building from the ground up demands vast resources, technical expertise, and political will. Countries like Germany, with existing enriched uranium, are in a slightly different position, but even there, hurdles remain. The Manhattan Project-like investment needed is simply enormous.

Archyde News: Is the non-proliferation regime at risk of collapse?

Dr. Sharma: If we see multiple European countries, or even one major nation, independently pursue nuclear weapons, it would, indeed, be a huge blow to the non-proliferation regime. Poland developing nuclear weapons would break with decades of policies on nuclear weapons limitations.

France and the UK: The Existing Nuclear Powers

Archyde News: What about France and the UK? They already possess nuclear arsenals.Are they facing similar pressures and shifts in their strategies?

Dr. Sharma: Absolutely. the UK, reliant on U.S. missiles,faces questions about long-term independence. france, with its more independent deterrent, has the option of “forward-deploying” its weapons. But also, even with that, France has questions, as forward deploying may not make a huge impact to deter on the front lines.

Archyde News: Poland has expressed interest in having the U.S. forward deploy its nuclear warheads. What are the prospects of that?

Dr. Sharma: Forward-deploying in Poland could enhance deterrence against Russian military aggression.

Archyde News: And could this spark a nuclear arms race on the continent?

Dr.Sharma: It is a significant concern.

The Role of Technology and New Threats

Archyde News: The potential for “low-cost proliferation” through technologies like 3D printing has been discussed. How seriously should we take such threats?

Dr. Sharma: Very seriously.Additive manufacturing could allow actors to secure or bypass customary choke points, circumvent inspections and controls. South Africa’s history serves as a reminder. We need to be prepared to adapt our non-proliferation strategies to this new threat landscape incorporating the challenges of the digital age.

Archyde News: Dr. Sharma, if you had one takeaway for our readers about the future of nuclear security in Europe, what would it be?

Dr. Sharma: The next few years will be critical. The decisions European nations make now will shape the continent’s security environment for decades. Increased instability and the potential threat of nuclear weapons is a worrying proposition. But ultimately, it is up to Europe to decide on how to deal with it. Now; the discussion about what Europe can do is on the table. The question is: what do you see as the most pressing challenge for Europe in navigating this new nuclear age? How do you think Europe should approach the new paradigm?
