US Weighs Nuclear Role for Poland

For a generation years, the American nuclear map in Europe barely moved. That period is ending. Defense News reported on June 2 that Washington is holding confidential talks on deploying nuclear-capable aircraft to Poland and the Baltic states, beyond the six countries that already host US nuclear weapons under NATO's sharing system. Poland's defence minister confirmed the talks. Lithuania's defence minister, Robertas Kaunas, acknowledged Lithuania's involvement, while refusing to give details because of classification rules.

Washington is doing this while reducing its conventional presence in Europe. Trump announced in May a withdrawal of 5,000 US soldiers from Germany, yet the same administration is offering to widen America's nuclear footprint. The message to eastern Europe is clear enough: fewer American boots on the ground, but a larger atomic umbrella overhead. For Malta, neutral and outside NATO, this is still not a distant argument. It is about how Europe's security order is being rewritten, and who gets to decide when nuclear risk moves closer to EU territory.

Two umbrellas, one map

France is building a second nuclear architecture across much of the same map. President Macron's "dissuasion avancée", or forward deterrence, now includes nine European partners, including Poland, Germany and three Nordic countries. The French model would see Rafale jets capable of carrying nuclear weapons temporarily deployed to partner bases.

The two systems sit in different political machinery. US nuclear sharing runs through NATO's Nuclear Planning Group, the forum where all alliance members except France coordinate nuclear posture. France has stayed out of the group since 1966 to protect its strategic independence, so Paris is working through bilateral arrangements outside NATO. It has also avoided criticising the American move, because doing so would antagonise Warsaw, its most important partner in forward deterrence.

Both Washington and Paris say the two efforts reinforce each other. In practice, they give partners very different levels of control. Under US nuclear sharing, pilots from the host country can deliver American weapons, and their governments take part in the planning. Under the French model, the decision to launch remains with the French president alone. Partners get exercises and consultations. The weapons, and the authority to use them, stay French.

Constitutional walls, silent parliaments

The expansion is running into legal barriers that have received little public attention. Lithuania's constitution bans weapons of mass destruction on its territory. When parliament tried to permit nuclear-armed ships to enter Klaipėda port, President Nausėda vetoed the measure, and the Seimas, Lithuania's parliament, upheld the veto by votes to four. Changing the constitution would require a two-thirds supermajority, which no current coalition can command.

Poland has a different problem: two executives pulling on the same file. President Nawrocki keeps a direct channel to Trump, separate from the defence ministry. He recently blocked ratification of a British defence treaty negotiated by Tusk's government, arguing that he had not been consulted. Washington is therefore dealing with two Polish centres of power at the same time.

In Estonia, the Riigikogu, Estonia's parliament, has discussed nuclear energy safety but has not touched weapons policy. There are no polls on whether Estonians would accept hosting nuclear arms. Germany already hosts US bombs at the Büchel airbase, yet the Bundestag has never voted on the arrangement. Across Europe, Finland is the exception: it is demanding a legislative process before nuclear posture changes.

Signal first, hardware later

The announcements matter politically, but the practical work is much slower behind. Nuclear sharing requires specialised storage vaults at host bases. These take years to build, certify and integrate with the aircraft that would deliver the weapons. Poland received its first three F-35s in May, but certifying pilots for nuclear missions is a separate process that takes several years.

Before weapons move, NATO has to decide what it is prepared to say publicly. The alliance summit in Ankara on July 7–8 will decide whether to formally open the door to nuclear expansion eastwards, or leave the idea as strategic signalling.

This is happening with arms control at its weakest point in half a century. New START, the last US-Russia nuclear arms treaty, expired on February 5. For the first time since 1972, no agreement limits either side's arsenal, and no inspections verify compliance. Russia has already widened its own nuclear doctrine to cover Belarus and is building a storage facility there, its first nuclear deployment beyond Russian borders since the Soviet collapse.

Europe's largest security shift in a generation is moving through classified channels and executive agreements. The question almost no capital wants to ask is the most basic one: who decided that the people who may end up living near these weapons should not get a vote?
