The US–NATO Rift & Europe's Rearmament

President Trump issued conflicting orders on European troop levels — directing 5,000 troops to Poland after having pulled the same number from Europe — causing confusion across NATO and disrupting military rotations. The reversal on a single canceled 4,000-troop Poland rotation alone cost $32 million in equipment-transport expenses. The whiplash is hitting troop morale and an already-strained US Army budget facing a $2–6 billion shortfall, and it deepens allied uncertainty about whether US posture decisions are durable. Allies cannot plan backfill against orders that flip week to week.

Speaking at the 82nd anniversary of the D-Day landings in Normandy, Defense Secretary Pete Hegseth urged European NATO partners to strengthen their own defense capabilities, declaring that 'America will lead' but allies must 'stand shoulder-to-shoulder' and that peace is guaranteed only through strength. He pointedly did not address the wars in Iran or Ukraine. French Defense Minister Catherine Vautrin responded that France is already 'in a rearmament process.' The choice of venue — the beaches where US troops died liberating Europe — turned a commemoration of shared sacrifice into a platform for a spend-more demand.

Fabrice Pothier, former NATO policy-planning director and CEO of Rasmussen Global, echoed ex-Secretary General Anders Fogh Rasmussen's call for a new European defense alliance amid doubts over US guarantees under Trump. Pothier urged European states — naming Poland and the Baltics — to trust their own capabilities, and argued Poland should transfer more air-defense interceptors to Ukraine because 'defending Ukrainian territory is the best way to defend Poland.' The comments landed amid strained US–Europe relations over both Ukraine and Middle East policy. Coming from NATO's own former planners, they move the hedge from private contingency to public doctrine.

A Foreign Affairs analysis argued that Trump's second-term policies — denigrating NATO, threatening to annex Greenland, withdrawing Ukraine aid, politicizing intelligence and halting Poland deployments — are forcing European allies to build independent military and intelligence capabilities. It cited Germany doubling its defense budget to $178 billion by 2029, European investment in satellite reconnaissance, air defense, drones and munitions, diversification of procurement away from US suppliers, and reduced intelligence-sharing with Washington over politicization fears. The piece concluded that if transatlantic trust is restored, these investments could yield a more powerful and balanced alliance. The throughline: the rupture is being treated as structural, not a one-term anomaly.

The US and NATO began the annual BALTOPS naval exercise in the Baltic on June 4 with about 20 vessels and 6,000 personnel from 15 nations — roughly half the size of the previous year's drills, because ships were redeployed to the Middle East and Arctic. Led by the USS Mount Whitney, the exercise ran through June 20 and focused on securing sea routes around the Swedish island of Gotland. German Rear Admiral Stephan Haisch, commander of the Rostock-based multinational Baltic headquarters, said the drills showed alliance unity but added he did not expect Moscow to trigger Article 5. The visible halving turned a reassurance exercise into a measure of US retrenchment.

The US prepared to propose at a June NATO force-generation conference an accelerated, compressed timeline to pull a portion of its forces from Europe, following the earlier announcement to withdraw 5,000 troops from the ~35,000 US service members in Germany. Washington gave European partners until the July 7–8 Ankara summit to present a plan to fill the gaps. In response, Chancellor Merz planned to host the E5 leaders (France, UK, Italy, Poland) in Berlin and is expected to invite NATO Secretary General Mark Rutte, while E5 defense ministers were set to meet in Paris on June 12 to coordinate command structures for a broader European conflict. The conference becomes the forcing mechanism that converts US absence into concrete European pledges.

Admiral Giuseppe Cavo Dragone, Chair of NATO's Military Committee, said European allies are progressing toward the 5%-of-GDP spending target demanded by the US, citing NATO's structured planning and stable Pentagon ties, and cautioned against overreacting to Russian drone incursions. In parallel, US Air Force General Alexus Grynkewich, NATO's top commander, publicly stated the US expects allies and Canada to add manned and unmanned aircraft and warships as Washington reduces its contributions to the NATO Force Model, citing an 'unhealthy co-dependence' on US forces. Per Der Spiegel, the number of US fighter jets available to NATO is set to fall by a third, with fewer destroyers and no submarines in the crisis pool. The two messages together — allies complying, US still cutting — frame the bind precisely.

At the Shangri-La Dialogue in Singapore on May 30, Defense Secretary Pete Hegseth delivered a major speech declaring that the era of the US subsidizing the defense of wealthy nations is over and calling on allies to raise defense spending to 3.5% of GDP. Though framed for Asia, the doctrine codified the same conditional-commitment logic Washington is applying to Europe, with Hegseth explicitly criticizing Western Europe. He warned the US is 'more than capable' of resuming operations against Iran if a nuclear deal collapses, and emphasized national interests over values — a transactional posture met with skepticism from Southeast Asian states. The speech is the clearest single statement of the burden-shift doctrine driving the NATO rift.

Global military spending hit a record $2.9 trillion in 2025, led by a 14% surge in Europe. US treaty allies (31 non-US NATO members plus Japan, South Korea, Thailand, Australia and the Philippines) collectively spent 111% of the US defense budget when adjusted for purchasing power, surpassing $1 trillion for the first time, even as the Pentagon's budget fell 7.5%. European and Canadian NATO allies alone accounted for 81% of US spending. In absolute terms allied spending still lagged about $200 billion behind the US, which retained over 20% of global military spending versus China's 12.7%. The data quantifies the burden-shift the rift is built on.

European politicians and defense officials — three EU politicians and four senior defense officials interviewed — warned that Russia could test NATO's Article 5 mutual-defense clause within one to two years, while Trump remains in office and before the EU has reinforced its forces. They feared a limited incursion, hybrid attack, or ambiguous action — such as a drone operation in the Baltic or Arctic — designed to sow discord rather than a full ground offensive, noting European defense spending has risen but will take years to materialize. Some NATO officials and Estonia's president downplayed the immediate threat, citing Russia's focus on Ukraine. The warning defines the precise danger window the US withdrawal opens.

On April 30 President Trump announced a review of the roughly 35,000–50,000 US troops in Germany, retaliation for Chancellor Merz saying Iran was 'humiliating' Washington at the negotiating table during the US–Israel war on Iran; Trump accused Merz of indifference to Iran getting nuclear weapons. On May 1 he expanded the threat to Italy and Spain, calling them 'horrible' for refusing to support US operations. The Pentagon was caught off guard — its own review had not recommended major pullbacks, and a 2025 congressional mechanism bars cutting European troop levels below 76,000 for over 45 days without certification. This impulsive, grievance-driven threat is the origin point of the entire troop-withdrawal saga that became the NATO rift.
