US weighs nuclear weapons for Poland

For a generation, the map of American nuclear weapons in Europe stayed fixed. That stability is ending. Defense News reported on June 2 that Washington is in confidential discussions about deploying nuclear-capable aircraft to Poland and the Baltic states, expanding beyond the six countries that currently host US nuclear weapons under NATO's sharing arrangement. Poland's defense minister confirmed the talks. Lithuania's defense minister Robertas Kaunas acknowledged his country's involvement while declining details on classification grounds.

Washington is simultaneously pulling conventional troops from Europe — Trump announced a 5,000-soldier withdrawal from Germany in May — while offering to extend its nuclear footprint. The atomic umbrella is being positioned as a replacement for soldiers on the ground.

Two umbrellas, one map

France is building a parallel nuclear architecture over the same geography. President Macron's "dissuasion avancée" (forward deterrence) now includes nine European partners, among them Poland, Germany, and three Nordic countries. France would temporarily deploy Rafale jets capable of carrying nuclear weapons to partner bases.

The two systems run through different channels. US nuclear sharing operates within NATO's Nuclear Planning Group (the body where all members except France coordinate nuclear posture). France, which has boycotted the NPG since 1966 to preserve strategic independence, works through bilateral deals outside NATO. Paris has stayed silent about the American expansion: criticizing Washington would alienate Warsaw, its most important forward-deterrence partner.

Both sides claim their efforts complement each other, but the mechanics diverge sharply. Under US sharing, host-nation pilots deliver American weapons, and their governments join the planning process. Under the French model, the launch decision stays with the French president alone. Partners receive exercises and consultations. The weapons, and the authority to use them, remain French.

Constitutional walls, silent parliaments

The expansion meets legal barriers that have drawn almost no scrutiny. Lithuania's constitution flatly bans weapons of mass destruction on its territory. When parliament tried to allow nuclear-armed ships at Klaipėda port, President Nausėda vetoed the measure and the Seimas (Lithuania's parliament) upheld the veto 95 to 4. Amending the constitution requires a two-thirds supermajority no current coalition can deliver.

Poland faces a different problem: dueling executives. President Nawrocki maintains a direct channel to Trump separate from the defense ministry, and recently blocked ratification of a British defense treaty that Tusk's government had negotiated, claiming he was not consulted. Washington is effectively negotiating with two Polish power centers at once.

In Estonia, the Riigikogu (Estonia's parliament) has discussed nuclear energy safety, leaving weapons policy entirely untouched. No polls exist on public attitudes toward hosting nuclear arms. Germany, which already hosts US bombs at the Büchel airbase, has never held a Bundestag vote on the arrangement. Across the continent, Finland stands alone in demanding a legislative process for nuclear posture changes.

Signal first, hardware later

The announcements carry political weight, but operational reality lags behind. The specialized storage vaults required at host bases take years to build, certify, and integrate with delivery aircraft. Poland received its first three F-35s in May, but pilot certification for nuclear missions is a separate, multi-year process.

Before any hardware moves, NATO must decide what to say. The alliance summit in Ankara on July 7–8 will determine whether to formally open the door to eastward nuclear expansion or keep the option in the realm of signaling.

This expansion would unfold in an arms-control vacuum. New START, the last US-Russia nuclear arms treaty, expired on February 5. For the first time since 1972, no agreement constrains either side's arsenal and no inspections verify compliance. Russia has expanded 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 most consequential security shift in a generation is advancing through classified channels and executive agreements. The question no capital seems willing to pose: who decided that the people living near these future weapons do not get a vote?
