A decade after NATO's 2% pledge, 17 of 31 members with a military finally cleared the bar — and the frontline overshot it

At the 2014 Wales Summit, NATO heads of state agreed to "move towards" spending 2% of GDP on defence within a decade — the pledge's target year was 2024. The World Bank's military-expenditure series (indicator MS.MIL.XPND.GD.ZS, sourced from the SIPRI Military Expenditure Database, database vintage last updated 2026-07-13) now carries 2024 figures for 31 of NATO's 32 members; Iceland, which has no armed forces, is not reported. On that series, 17 of the 31 members reported defence spending at or above 2.0% of GDP in 2024. In 2014, the year the pledge was made, 3 members did so — the United States (3.68%), the United Kingdom (2.18%) and Greece (2.37%). In 2021, the last full year before Russia's full-scale invasion of Ukraine, the count was 6. Eleven members therefore crossed the 2% line for the first time, on this measure, between 2021 and 2024. Poland reported the highest ratio in the alliance in 2024 at 4.15% of GDP, ahead of the United States at 3.42%, Estonia at 3.37%, Latvia at 3.26%, Greece at 3.13% and Lithuania at 3.12%. Fourteen members remained below 2% in 2024, including Germany (1.89%), Italy (1.61%), Spain (1.43%), Canada (1.31%), Belgium (1.28%) and Luxembourg (0.96%). Sweden, which joined the alliance in 2024, came in at 1.9977% — 0.002 percentage points short of the line.

The following is analysis, not fact. The pledge's arithmetic is easy to state and hard to game: a ratio of two independently reported numbers, defence outlays over GDP, filed the same way for every member. Read across all 31 members at once, the decade did not move the alliance uniformly — it moved the map. The three largest decade-long increases all belong to states bordering Russia or Belarus: Latvia (+2.28 percentage points from 2014 to 2024), Poland (+2.25) and Lithuania (+2.23), with Estonia fourth (+1.48). The frontline did not merely reach 2%; it overshot the target by a wide margin, with Poland now spending a larger share of its economy on its military than the United States does. That inversion — a European member outspending Washington on this ratio — did not exist in 2014, when the U.S. share (3.68%) was the highest in the alliance, and only two European members — the U.K. (2.18%) and Greece (2.37%) — cleared 2% at all. The laggards cluster by geography too. Of the 14 members still under 2% in 2024, the largest economies among them — Germany, Italy, Spain, Canada — sit farthest from the eastern border and carry the biggest absolute defence budgets, so a sub-2% ratio still buys substantial capability. The ratio measures effort against economic size, not capability; a reader should not read Poland's 4.15% as more military than Germany's 1.89% in dollar terms. Two members' shares were lower in 2024 than in 2014: the United States (-0.26 points) and Croatia (-0.01). The U.S. decline is the mechanical result of a growing denominator, not a shrinking budget — U.S. defence outlays rose over the decade while GDP rose faster — and it remains the alliance's second-highest ratio. Every other member with data in both years spent a larger share in 2024 than in 2014.

The strongest counter is definitional: this is SIPRI's measure, not NATO's own. NATO's internal defence-expenditure methodology differs — it counts items such as military pensions and some paramilitary and R&D spending differently, and applies its own GDP figures — and on NATO's own accounting the number of members at 2% in 2024 is higher than the 17 reported here. A reader who takes NATO's press figure and this SIPRI-derived count as the same series will find them in conflict; they are measuring slightly different things. The 2% line is a single threshold, so a member reported at 1.92% here (the Netherlands, Turkey, Czechia) may sit just above the line on NATO's books. A second caution: 2024 GDP figures are still subject to revision, and a ratio moves when either its numerator or denominator is revised. And the pledge itself was "move towards" 2%, not a binding floor — whether 17 of 31 constitutes success or failure is a political judgment this piece does not make. The count and the ranking are the facts; their sufficiency is contested.

The same SIPRI series reads differently from Moscow and from the alliance's eastern edge. Russia's own military-expenditure share rose from 3.58% of GDP in 2021 to 7.05% in 2024 on this measure, and Ukraine's reached 34.48%. Russia's government has characterised NATO's buildup as an offensive threat justifying its own; NATO has characterised the same numbers as a deterrent response to Russia's 2022 invasion. The dataset cannot adjudicate which framing is correct — it can only show that both the alliance's frontline and Russia raised their shares in the same window, and that the frontline states raised theirs the most within NATO.

A defence correspondent covers one country's budget: Berlin's shortfall, Warsaw's surge, Washington's topline. Reading all 31 members' ratios in a single pull shows the shape no single-country desk sees — that the 2% pledge did not lift the alliance evenly but redistributed it toward the map's eastern edge, until the member closest to Russia (Poland, 4.15%) now spends a larger share of its economy on defence than the superpower that anchors the alliance (United States, 3.42%). The story of the decade is not that NATO hit its target; it is that geography, not the target, decided who overshot and who is still short by two-thousandths of a point.
