US Considers Expanding Nuclear Umbrella Over Europe to Reassure NATO

The US is currently engaged in confidential discussions regarding the deployment of nuclear weapons to additional European NATO states, a move designed to reassure allies amid a shifting American defense posture, the Financial Times reported on June 2.

According to three individuals briefed on the talks, US officials are open to expanding deployments beyond the six countries that currently host American nuclear-capable bombers. The discussions are driven by widespread concerns across Europe following White House’s efforts to withdraw US troops and critical conventional weapon systems from the continent.

Expanding the nuclear sharing program would allow more allied countries to host US dual-capable aircraft (DCA), which can deliver nuclear strikes. The expansion aims to demonstrate Washington’s commitment to maintaining a nuclear umbrella over Europe, even as NATO members are pressed to assume more of the conventional defense burden.

Sources told the Financial Times that countries along NATO’s eastern flank, including Poland and several Baltic states, have expressed interest in hosting DCA bases. Polish officials have openly discussed their desire to host nuclear weapons. Warsaw recently joined a new French initiative exploring the temporary relocation of parts of France’s nuclear deterrent to allied European territory, while former Polish President Andrzej Duda previously urged the US to expand the DCA initiative to his country.

US Launches Nuclear-Capable Minuteman Missile as Russia Begins Strategic Drills

Interest among eastern allies has been heavily catalyzed by Russia’s ongoing full-scale invasion of Ukraine and repeated threats from Vladimir Putin regarding the Kremlin’s nuclear capabilities. However, one source cautioned that while talks are ongoing within NATO channels, an agreement to expand the hosting arrangement is not imminent, according to the Financial Times.

NATO's existing nuclear sharing program includes Belgium, Germany, Italy, the Netherlands, Turkey, and the UK. These nations are approved to host US dual-capable aircraft and forward-deployed nuclear bombs. The weapons remain securely guarded by US troops, and Washington retains sole authorization for their use. Under this Cold War-era arrangement, allied air groups utilize F-35, F-15, and Tornado jets to participate in joint exercises, serving as a platform for non-nuclear allies to guarantee their security, the Financial Times wrote.

Europe’s Hidden Arsenal: Can France and the UK Forge a True Nuclear Deterrent?

Apr 28, 2025 16:56

Decisions by the Trump administration to cancel planned deployments of key weapons systems and shift more military assets to Asia have startled several NATO allies. Financial Times notes that European leaders fear these moves could leave significant vulnerabilities in the continent’s deterrence capabilities.

While European allies have promised to drastically increase defense spending and invest in conventional military assets currently supplied by the US, the nuclear umbrella is widely viewed as irreplaceable. Following a meeting of alliance foreign ministers last month, NATO Secretary-General Mark Rutte stated there was a “common understanding that whilst the US will pivot more towards other theatres… the overall deterrence and defence in Europe has to stay the same,” the Financial Times reported.

The US strategy to reassure its eastern flank coincides with a growing European effort to build an autonomous deterrence strategy. Driven by lingering doubts over the long-term reliability of Washington’s security guarantees, several Scandinavian nations had turned to Paris for protection.

Norway recently signed an agreement to join France’s “nuclear umbrella,” with Prime Minister Jonas Gahr Støre citing Russia’s military rearmament as the catalyst. The move makes Norway the ninth country to align with France’s forward deterrence framework, following similar overtures from Sweden and Denmark, as European allies solidify a backup plan in case US military support wavers.
