What happened

NATO leaders met in Ankara, Turkey, on July 7 and 8 for the alliance's 2026 summit, where member countries' collective defense spending was projected to reach approximately $1.8 trillion for the year -- a marker of the continued increase in military budgets across the alliance in recent years.

What we know

The Ankara summit brought together heads of state and government from NATO's member countries for discussions covering the alliance's defense posture, spending commitments, and coordination among allies. Rising defense budgets across NATO member states have been a consistent trend in recent years, driven by member countries working toward the alliance's spending guidelines and responding to broader security concerns in Europe.

Why it matters

Defense spending levels among NATO allies have long been a point of discussion within the alliance and in U.S. foreign policy circles specifically, since the United States has historically been among the largest contributors to NATO's collective defense spending. Progress toward higher spending among European allies is often framed as a matter of more balanced burden-sharing within the alliance. The scale of collective spending reflected in this year's figures signals a continued shift compared to the lower defense budgets common among many European members in the years following the Cold War.

Background

NATO's collective-defense principle, enshrined in Article 5 of the alliance's founding treaty, commits members to treat an attack on one as an attack on all. Member countries have periodically set target benchmarks for defense spending as a share of GDP, and compliance with those benchmarks has varied significantly across the alliance's member states over time, making it a recurring subject at NATO summits.

Spending targets are typically expressed as a percentage of each member's gross domestic product, which means the same target represents very different absolute amounts across an alliance that includes some of the world's largest economies alongside much smaller member states. That disparity has long made burden-sharing a point of friction within the alliance, particularly in discussions between the United States -- historically the largest single contributor to NATO's collective military spending -- and European members.

The bigger picture

Defense spending pledges made at summits are political commitments rather than binding legal obligations, and member states have a mixed record of meeting them on the promised timeline. Analysts who track alliance spending typically look at both the headline pledges and the year-over-year budget trends in individual member countries to assess whether commitments are translating into actual military investment.

What happens next

NATO members are expected to continue reporting progress toward defense spending commitments at future alliance meetings, with the pace of increases likely to remain a topic of discussion among member governments and in U.S. foreign policy debates about the alliance's burden-sharing arrangements.
