The Trump administration is reportedly considering whether to expand the U.S. nuclear presence in Europe, a move that could reassure anxious NATO allies but also risk undermining one of President Donald Trump’s central foreign policy goals: pushing Europe to take more responsibility for its own defense.
The idea has not been finalized. According to Reuters, citing a Financial Times report, U.S. officials have discussed expanding nuclear weapons hosting arrangements in Europe, including the possible deployment of more nuclear-capable aircraft to additional NATO countries. Poland and the Baltic states have been mentioned as possible locations because of their proximity to Russia and their strong support for a tougher NATO posture.
The proposal comes as the Trump administration signals that Europe should prepare for a future with fewer U.S. troops on the continent. Secretary of State Marco Rubio recently said there is broad recognition that U.S. force levels in Europe will eventually be lower than they have been historically, even as he described NATO as important to American national security.
That message reflects a long-running U.S. complaint. For decades, presidents from both parties have argued that European allies rely too heavily on American military power. Trump has been more blunt than most, repeatedly pressing NATO members to spend more and do more for their own defense.

In some ways, that pressure is working. European defense spending has risen sharply since Russia’s full-scale invasion of Ukraine. SIPRI reported that European military expenditure increased by 14% in 2025 to $864 billion, with Germany’s spending rising by 24% to $114 billion.
That should be exactly the outcome Washington wants. A stronger Europe means the United States can shift more attention and resources toward other priorities, including China, the Indo-Pacific and homeland defense.
But expanding America’s nuclear role in Europe could send the opposite signal.
For NATO allies near Russia, the appeal is obvious. Countries such as Poland and the Baltic states worry that Moscow could test the alliance’s resolve, especially if it believes the United States is reducing its conventional presence. Hosting U.S. nuclear-capable aircraft or related assets would be seen by some officials as a powerful symbol that Washington’s security guarantee remains firm.
Polish leaders have also become more open about nuclear deterrence debates. Prime Minister Donald Tusk has previously suggested that Poland must consider all security options in a more dangerous Europe, though Poland does not currently possess nuclear weapons of its own.
Still, expanding nuclear deployments would not be as revolutionary as it may sound. NATO already has a nuclear-sharing arrangement dating back to the Cold War. Under that system, U.S. nuclear weapons are stored in Europe and could be delivered by allied aircraft if Washington authorized their use. The purpose was to deter the Soviet Union while also discouraging allies from building their own nuclear arsenals.
The problem is that today’s strategic environment is different.
In the 1950s and 1960s, Western Europe was still rebuilding after World War II and faced a massive Soviet military presence. U.S. nuclear guarantees helped stabilize the alliance. In 2026, Europe is wealthy, technologically advanced and already increasing defense spending. The central U.S. challenge is no longer persuading Europe that America will always do more. It is persuading Europe to do more itself.
That is why a larger U.S. nuclear footprint could backfire. If European governments believe Washington will continue strengthening its nuclear and conventional guarantees, their incentive to make difficult long-term defense investments may weaken.
Defense spending is politically difficult. European leaders face voters worried about energy costs, slow growth, housing pressure and social welfare systems. Many politicians would rather preserve domestic spending than make deep investments in military readiness. Stronger U.S. guarantees could give them an excuse to slow down.
That would undercut Trump’s own burden-sharing strategy.
A smarter approach would preserve NATO’s nuclear deterrent while keeping the pressure on Europe to build credible conventional forces. The United States can remain committed to NATO without making every European security problem dependent on more U.S. deployments.
This is especially important because nuclear weapons do not solve Europe’s most immediate defense gaps. The alliance needs more air defense, drones, ammunition, logistics capacity, armored units, naval assets and industrial production. Reuters recently reported that the U.S. is urging European NATO allies and Canada to increase contributions of aircraft, drones, refueling planes and naval vessels as Washington reduces the availability of some U.S. forces to the alliance.
Those are the capabilities Europe must build if it wants to deter Russia without permanent dependence on American power.
There is also an escalation risk. Russia would almost certainly portray expanded U.S. nuclear deployments in Eastern Europe as a provocation. Moscow’s objections should not dictate NATO policy, but alliance leaders should still consider whether the move would increase deterrence or simply fuel another round of nuclear signaling.
Supporters of the plan may argue that nuclear deployments are necessary because Russia itself has relied heavily on nuclear threats since invading Ukraine. They may also argue that visible U.S. nuclear commitments could discourage European countries from pursuing their own nuclear weapons programs.
Those arguments should be taken seriously. Nuclear reassurance has been part of NATO’s success for decades. But reassurance can become dependency if it is not paired with real European responsibility.
The Trump administration should be careful not to confuse a symbolic show of strength with a sustainable strategy. If the goal is to make NATO more balanced, Europe must continue building the conventional forces needed to defend its own neighborhood. If Washington expands nuclear guarantees too far, it may relieve exactly the pressure that has finally pushed Europe to act.
The better path is not to abandon NATO or weaken deterrence. It is to keep U.S. nuclear commitments credible while making clear that Europe’s security cannot remain built around automatic American escalation.
Trump has often argued that allies must pay more and carry more of the burden. On that point, he is getting results. A new nuclear expansion in Europe could make allies feel safer in the short term, but it could also slow the defense buildup the United States has spent years demanding.
That is the contradiction at the heart of the proposal. A stronger U.S. nuclear posture may look like toughness. But if it encourages Europe to fall back into dependence, it could leave NATO less balanced and America more burdened in the long run.
Why It Matters
The issue matters because NATO is trying to adjust to two pressures at once: Russia’s continued threat and America’s desire to reduce its conventional burden in Europe. Expanding U.S. nuclear deployments could reassure allies, but it could also reduce Europe’s incentive to keep investing in its own military strength.
It also matters because nuclear posture changes carry diplomatic and strategic risks. Any move involving U.S. nuclear weapons in Europe would be closely watched by Russia, NATO allies and nonproliferation experts.
What Comes Next
The Trump administration has not made a final decision on expanding nuclear deployments in Europe. NATO discussions are likely to continue as allies prepare for upcoming summit meetings and negotiate how to balance reassurance, deterrence and burden-sharing.
European governments will also face pressure to keep increasing defense spending, especially in areas such as air defense, drones, naval assets, ammunition production and logistics. If Washington wants Europe to take more responsibility, it will need to avoid policies that make allies more dependent on U.S. protection.
Some commentators have framed Europe’s defense debate as part of a broader push for greater military autonomy amid uncertainty over long-term U.S. commitments.
