More European NATO members could be added to the U.S. nuclear-sharing system, extending hosting beyond the six current states — the U.K., Germany, Italy, the Netherlands, Belgium and Turkey.
Poland and some Baltic countries are seen as potential candidates, according to the Financial Times, as Washington reassesses its conventional military role in Europe and allies boost defense spending.
NATO said work on adapting its nuclear deterrence posture has been underway for years and is not tied to any single U.S. decision on conventional forces in Europe.
F-35-linked defense groups including BAE Systems, Lockheed Martin, Rolls-Royce, Northrop Grumman and RTX could benefit, because wider deployment would require more dual-capable aircraft and long-term maintenance.
The discussions come after Trump pledged thousands of new troops to NATO's eastern flank and after NATO chief Mark Rutte renewed vows to defend every inch of allied territory following a Russian drone strike in Romania.
As Europe's defense spending soars, can expanding nuclear hosting fix the critical readiness gaps on NATO's eastern flank?
With Poland eager to host nuclear arms, what new 'red line' does this potential deployment draw for Russia in Eastern Europe?
NATO’s Nuclear Dilemma: The 2026 Debate Over U.S. Nuclear Expansion to Eastern Europe and Its Geopolitical Fallout
Overview
As of June 2026, the United States and NATO allies are holding confidential talks about expanding U.S. nuclear weapons hosting in Europe, especially on NATO’s eastern flank. This debate comes as the White House plans to reduce conventional military support, prompting European nations to boost defense spending and consider less reliance on Washington. Concerns about U.S. commitment have led some European governments to openly discuss independent nuclear deterrence for the first time since the Cold War. French President Macron’s proposal to extend France’s nuclear umbrella reflects a growing desire among allies for stronger nuclear assurances and a more robust European defense posture.
