Poland is signaling increased interest in developing nuclear weapons as a means to deter threats from Russia.
Statements from leadership
Prime Minister Donald Tusk has described a long-term aim of greater autonomy in nuclear deterrence ahead of a March 3 government meeting.
He confirmed ongoing talks with France and other European partners about the “advanced nuclear deterrence” program proposed by French President Emmanuel Macron.
He linked Poland’s stance on nuclear security to heavy investments planned for future nuclear power plants.
“We will cooperate with our allies… as our capabilities increase, we will try to prepare Poland for autonomous action in this matter,” Tusk said.
Political backing and public sentiment
President Karol Nawrocki has publicly advocated for Poland to pursue a nuclear deterrent as protection against Russian threats.
Nawrocki reiterated strong support for the idea in February, and former President Andrzej Duda raised the issue in 2025 while welcoming Macron’s proposal and expressing openness to hosting allied weapons.
Poland’s discussions emphasize multilateral paths rather than an immediate independent arsenal.
Talks with France focus on participating in a shared deterrence framework that could include consultations, joint exercises, and planning without transferring weapon ownership.
Poland has also consulted Sweden, Denmark, and other countries invited to Macron’s initiative as part of broader European deliberations.
That approach aims to reduce reliance on U.S. nuclear guarantees while keeping NATO cohesion intact.
Public opinion in Poland shows notable support for enhanced nuclear capabilities, with polls indicating around half of respondents favoring steps toward a deterrent.
Legal constraints and options
Poland is a party to the Nuclear Non‑Proliferation Treaty, which it signed in 1969, and the treaty bars acquisition or development of nuclear weapons by non‑nuclear states.
Any unilateral move to build an independent arsenal would require withdrawal from the NPT and would likely trigger sanctions and diplomatic isolation.
Poland could instead pursue NATO nuclear sharing arrangements, where allies host U.S. weapons and train delivery personnel without owning the warheads.
Alternatively, Poland could join extended deterrence measures such as France’s proposed European framework that offers consultation and guarantees without physical possession of weapons.
Global context
Nine countries are known to possess nuclear weapons: the United States, Russia, the United Kingdom, France, China, India, Pakistan, and North Korea.
Israel is widely believed to possess nuclear weapons but has not declared them.
While several NATO members host U.S. weapons under sharing agreements, no new European states have developed independent arsenals since the Cold War era.
The NPT framework has been central to preventing wider proliferation among nations.
