US Weighs Nuclear Aircraft for Poland

For more than 30 years, the American nuclear map in Europe barely moved. It is moving now. Defense News reported on June 2 that Washington is holding confidential talks on deploying nuclear-capable aircraft to Poland and the Baltic states, pushing beyond the six countries that already host US nuclear weapons under NATO’s nuclear-sharing system. Poland’s defence minister confirmed the talks. Lithuania’s defence minister, Robertas Kaunas, acknowledged his country’s involvement, while refusing details on classification grounds.

The timing matters. Washington is at the same time pulling conventional troops from Europe, after Trump announced in May that 5,000 soldiers would be withdrawn from Germany. The offer to widen the American nuclear footprint is, in effect, being placed where soldiers used to stand. For Ireland, with its long unease around European defence integration, that distinction will not feel academic.

Two umbrellas, one map

France is building its own nuclear architecture over much the same territory. President Emmanuel Macron’s “dissuasion avancée”, or forward deterrence, now covers 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 beside each other, but they do not work the same way. US nuclear sharing runs through NATO’s Nuclear Planning Group, the forum where all allies except France co-ordinate nuclear posture. France has stayed outside that group since 1966, guarding its strategic independence, and instead makes bilateral arrangements beyond NATO structures. Paris has said little about the American move, for an obvious reason: attacking Washington’s plan would risk alienating Warsaw, its most important partner in forward deterrence.

Both Washington and Paris describe their efforts as complementary. The machinery tells a more complicated story. Under US sharing, pilots from the host country can deliver American weapons, and their governments take part in planning. Under the French system, 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 legal obstacles are serious, though they have attracted little public scrutiny. Lithuania’s constitution bans weapons of mass destruction on its territory. When parliament tried to allow nuclear-armed ships into Klaipėda port, President Gitanas Nausėda vetoed the measure, and the Seimas, Lithuania’s parliament, upheld the veto by 95 votes to 4. Changing the constitution would require a two-thirds supermajority that no current coalition can command.

Poland has a different difficulty: two executive centres pulling foreign policy in different directions. President Nawrocki maintains a direct channel to Trump, separate from the defence ministry. He recently blocked ratification of a British defence treaty negotiated by Tusk’s government, saying he had not been consulted. Washington is, in practice, negotiating with two Polish power bases at once.

In Estonia, the Riigikogu, the national parliament, has discussed nuclear energy safety but has left nuclear weapons policy untouched. There are no polls on whether Estonians would support hosting nuclear arms. Germany, which already hosts US bombs at Büchel airbase, has never held a Bundestag vote on the arrangement. Across Europe, Finland is the outlier, insisting on a legislative process before any nuclear posture change.

Signal first, hardware later

The political signal is immediate. The operational reality would take much longer. Host bases need specialised storage vaults, and those have to be built, certified and integrated 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 years.

Before anything is moved, NATO has to decide what language it is willing to use. The alliance summit in Ankara on July 7-8 will decide whether to formally leave the door open to nuclear expansion eastwards, or keep the idea as a signal rather than a plan.

All of this is happening without the guardrails that shaped the previous nuclear age. New START, the last remaining 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 widened its own nuclear doctrine to include Belarus and is building a storage facility there, its first nuclear deployment beyond Russian borders since the Soviet collapse.

Europe’s biggest security shift in a generation is moving through classified talks and executive channels. The awkward question is also the democratic one: who decided that the people living beside these future weapons would not get a vote?
