Europe’s Nato planning shifts toward rearmament as U.S. commitment remains uncertain
Europe rethinks NATO defense

After Nato’s Ankara summit eases immediate fears of a rupture, Europe and Ukraine still face a volatile security environment shaped by Russia’s war and uncertainty over U.S. policy. The central challenge now is whether European allies can rebuild military capacity within the next two to three years while preserving the alliance’s deterrence credibility.

Highlights

  • Ankara summit resulted in increased support for Ukraine, enhanced NATO collective defence, and recognition of Europe's rising defence spending and military modernisation.
  • Europe is accelerating rearmament planning over the next two to three years to replace American conventional capabilities amid uncertainty over future U.S. support.
  • Structural limits to a more Europeanised NATO persist as European states form smaller coalitions, while the U.S. remains vital due to arms exports and continued military experimentation in Ukraine.

Summit outcome and rearmament timetable

As argued in the Financial Times, the Ankara summit delivers stronger backing for Ukraine, renewed support for collective defence and nuclear deterrence, and recognition of Europe’s rising defence spending, production and military modernisation. The article says the more difficult phase begins now, as Kyiv and European capitals confront an aggressive Russia and a U.S. position that shifts between support, disengagement and hostility.

The text says there is no prospect of a ceasefire between Kyiv and Moscow. While Ukraine is gaining an advantage through drone operations and long-range strikes on Russian refineries and arms factories, it remains weak on recruitment, and President Volodymyr Zelenskyy is reorganising his cabinet for the fourth time in as many years.

For European planners, the piece outlines two scenarios, an immediate contingency involving a sudden Russian attack on the Baltics, or broader military aggression in a few years. In the near term, U.S. support remains vital, but over a longer horizon Europe is moving to replace a range of American conventional capabilities, making rearmament over the next two to three years the best-case path described in the article.

Alliance structure and Europe’s strategic risks

A more Europeanised Nato still faces structural limits because the alliance’s military architecture is built around U.S. leadership. The article says plans are already under way to replace U.S. four-star officers at the joint force commands in Norfolk, Naples and Brunssum with Europeans, but it argues that Washington’s role as an offshore political balancer in Europe is far harder to replicate.

That pressure is pushing European states toward smaller coalitions such as the Joint Expeditionary Force, while also increasing the need for broader all-European arrangements. The piece says such coalitions will require unusually high levels of solidarity, especially as southern Europe watches Middle East escalation and western European governments weigh the security implications of President Donald Trump’s demands for Greenland.

The article also highlights concerns among smaller European countries about the reliability of France, the UK and Germany, including the risk of pro-Russian populist leadership or regional dominance through defence spending. Even so, it concludes that a full transatlantic split is not yet under way, because Europe remains an indispensable market for U.S. arms and Ukraine continues to serve as a testing ground for American weapons, doctrine and tactics.

We previously reported on the U.S. Senate debate over Section 815 in the National Defense Authorization Act, which would restrict Pentagon suppliers from conducting stock buybacks, paying dividends, or making other capital distributions without Defense Department approval. The proposal, backed by supporters as a way to force more reinvestment into defense production, has drawn pushback from business groups and some lawmakers who warn it could deter investment and add uncertainty for the defense industrial base as Washington tries to expand capacity.
