NATO is evaluating the deployment of additional U.S. nuclear weapons in Europe to strengthen its Eastern European and Scandinavian flanks in response to Russian threats. Potential host nations include Poland, Finland, and Lithuania. Finland has lifted its ban on the import and transit of nuclear arms, while Lithuania is debating legislation to relax constitutional prohibitions on stationing such weapons.

A policy tension has emerged regarding the specific nature of participation in NATO’s ‘Nuclear Sharing’ programme. Following talks in Brussels, Polish Deputy Defense Minister Paweł Zalewski clarified that while Poland seeks to be an active participant in NATO’s nuclear deterrence, the country does not want nuclear warheads physically present on its territory.

Defense Minister Władysław Kosiniak-Kamysz has since clarified that Poland remains interested in participating in the Nuclear Sharing program and is not withdrawing from discussions regarding the nuclear dimension of deterrence. Zalewski noted that Poland has gained the opportunity to participate in the Dual Capabilities Airborne (DCA) program, which serves as a precursor to Nuclear Sharing.

This stance has drawn criticism from former Defense Minister Mariusz Błaszczak, who argued that refusing the presence of warheads effectively means withdrawing from the Nuclear Sharing programme, as the initiative requires participating nations to provide infrastructure and transport capabilities for American weapons stationed on their soil. 

Regarding broader bilateral security, Zalewski indicated that talks are underway concerning several potential locations for permanent American military bases, noting that the U.S. has significant interests in the region.
