Pentagon slashes NATO reinforcement pledges

For seventy-five years, NATO rested on a simple exchange: the United States guaranteed Europe's defense, and Europe hosted American forces. Military planning documents are now dismantling that arrangement on two fronts at once, pulling soldiers out physically while cutting the wartime reinforcement pledges that NATO's war plans depend on.

On May 19, SACEUR General Alexus Grynkewich, NATO's supreme allied commander in Europe, told alliance defense chiefs that "additional redeployments should absolutely be expected" (Stars and Stripes). The same week, the Pentagon moved to formally reduce US contributions to the NATO Force Model, the classified framework determining how many troops each ally pledges for wartime deployment, according to three sources cited by Reuters (Military Times).

The visible track has already pulled 5,000 troops from Europe, including a cancelled armored brigade rotation to Poland and a long-range missile battalion from Germany (Defense News). The less visible track cuts into the Force Model itself, which governs how many reinforcements arrive in a crisis. NATO's regional defense plans, agreed at the 2023 Vilnius summit, were sized around specific US commitments. Without those commitments, the plans no longer work.

NATO Secretary-General Mark Rutte called the shift "expected" and "only right" (Brussels Signal). Grynkewich set the timeline for European self-sufficiency at "certainly by 2035" (Breaking Defense). That leaves a five-to-nine-year window in which Europe's old security guarantee is gone and its replacement does not yet exist.

Iran Drains the Stockpile

The US war with Iran, Operation Epic Fury launched in February 2026, has consumed 45 to 80 percent of several categories of US precision munitions, according to CSIS (CSIS). The Pentagon notified the UK, Poland, Estonia, Lithuania, and Norway of "serious delays" to deliveries of HIMARS rockets, NASAMS interceptors, and Javelin missiles (Euromaidanpress). Europe is losing American soldiers and American weapons at the same time.

Germany Punished, Eastern Flank Exposed

Germany absorbed the sharpest blow. Chancellor Merz had publicly attacked US conduct of the Iran war, reportedly telling a German audience his children should not move to America. Washington responded by withdrawing 5,000 troops from German soil and cancelling the planned Tomahawk cruise missile deployment. Merz conceded on May 19 that the missile deal is effectively dead (NTZ).

Germany's deeper constraint is people, not money. The Bundeswehr fields 120,000 active soldiers against a NATO requirement of roughly 280,000 by 2030. Berlin budgeted €108 billion for defense in 2026, but spending alone cannot conjure recruits. A May survey found only 41% of Germans still view the US as an ally (YouGov).

On the eastern flank, the withdrawal has split allies into competing tiers. Poland, spending 4.48% of GDP on defense, sent officials to consult Deputy Defense Secretary Elbridge Colby, architect of a doctrine he calls "NATO 3.0," which assigns conventional defense of Europe to Europeans so the US can shift forces toward China (Defence24). Poland earned the label "model ally." Its cancelled 4,000-troop brigade rotation stands anyway; equipment arrived in Polish ports without soldiers to operate it.

Estonia's foreign minister called US decisions "uncoordinated" and pressed allies to "urgently determine the reasoning and next steps" (ERR). Romania pivoted to hosting temporary US equipment, earning Washington's praise for opening bases during the Iran campaign.

July in Ankara

The NATO leaders' summit on July 7–8 will test whether these Force Model cuts get cemented into formal alliance commitments. Congressional resistance offers a partial brake. Republican hawks on the Armed Services committees have threatened consequences if the Pentagon drops below the statutory floor of 76,000 US troops in Europe (Notus). But Colby's logic, that Europe must handle its own conventional defense so America can face China, predates Trump and would outlast him.

The Americans are leaving. Grynkewich confirmed it. What European capitals do between now and 2035 determines whether the gap stays a planning problem or becomes a security crisis.
