Eastern Europe is teetering on the edge of a nuclear transformation. NATO’s potential move to deploy U.S. B61 tactical nuclear weapons in Poland—or even Ukraine—could shatter decades-old agreements and redraw the region’s security map.
As Belarus hosts Russian warheads and Kaliningrad becomes a fortress, the balance of power is precariously shifting.
Will this high-stakes gamble deter Moscow, or are we inching closer to an uncontrollable arms race in Europe?
Poland’s Nuclear Ambitions
Poland’s President Andrzej Duda has explicitly stated the country’s readiness to participate in NATO’s nuclear sharing program, citing concerns over Russia’s militarization of Kaliningrad. (ref)
However, Polish Prime Minister Donald Tusk has called for careful national deliberation, describing it as a “massive idea” requiring thorough discussion.
The potential arrangement would make Poland the sixth NATO member capable of deploying U.S. tactical nuclear weapons.
Current Nuclear Sharing Framework
The existing NATO nuclear sharing arrangement encompasses five nations—Belgium, Germany, Italy, the Netherlands, and Turkey—with approximately 100 U.S. nuclear warheads stored across these countries. (ref)
These nations can deploy American B61 tactical nuclear bombs on their fighters under NATO control.
The program recently underwent modernization with the introduction of the more powerful B61-12 variant and the F-35A stealth fighter.
Russian Response & Strategic Implications
Moscow has responded firmly to the possibility of nuclear weapons in Poland, promising “all the necessary retaliatory steps” to ensure its security.
The situation has become more complex since Russia deployed tactical nuclear weapons to Belarus in 2022.
This nuclear positioning has created a new strategic reality in Eastern Europe, with both sides adjusting their deterrence postures.
Technical & Political Considerations
The modernized B61-13 variant represents a significant upgrade in NATO’s nuclear capabilities (ref), with an adjustable yield ranging from 0.3 to 360 kilotons. Poland’s acquisition of 32 F-35s by 2030 provides the technical foundation for nuclear-sharing capabilities.
However, the alliance faces internal debates about nuclear policy, with some members questioning the future of nuclear-sharing arrangements.
The program’s expansion eastward would require breaking with the 1997 NATO-Russia Founding Act (ref), which some allies are reluctant to abandon.
Infrastructure & Security Requirements
Implementing nuclear sharing in Poland would require substantial infrastructure investments, including specialized storage facilities, security systems, and personnel training.
The U.S. Department of Defense estimates that establishing nuclear-capable bases costs hundreds of millions of dollars, with ongoing maintenance and security requirements adding significant annual expenses.
These facilities must meet stringent NATO nuclear certification standards and maintain continuous surveillance.
Impact on Regional Security Architecture
The potential deployment would fundamentally alter the security landscape in Central and Eastern Europe. Baltic states have supported Poland’s initiative, viewing it as an enhanced deterrent against Russian aggression.
However, neutral countries like Finland and Sweden, despite their recent NATO membership bids, maintain reservations about nuclear weapons deployment near their borders.
This development could trigger a broader reorganization of Europe’s security architecture and influence future arms control negotiations.
