NATO Defense Ministers Face Challenges in Reaching Consensus on Increasing Defense Budget Priorities

NATO defense ministers convened in Brussels on Thursday and reached a broad consensus on the pursuit of a substantial increase in military spending to 5 percent of GDP among member states. However, the discussions unveiled significant divisions concerning the timeline for achieving these targets and what expenditures should be included, setting the stage for tough negotiations ahead of the organization’s upcoming summit scheduled for June 24-25 in The Hague.

“There’s broad support. We are really close,” emphasized NATO Secretary General Mark Rutte following the talks. He expressed confidence that a resolution would be reached by the next summit, outlining a compromise plan under consideration: a target of 3.5 percent of GDP for core military spending and an additional 1.5 percent for broader security-related investments, including infrastructure, to be achieved by 2032.

Mounting U.S. Pressure

The momentum for increased defense outlays has been driven by growing pressure from the United States. Washington initially proposed the ambitious 5 percent target late last year, warning that American security commitments in Europe could waver without greater contributions from allies. “To be an alliance, you got to be more than flags. You got to be formations. You got to be more than conferences. You need to be, keep combat-ready capabilities,” stated U.S. Defense Secretary Pete Hegseth as he arrived at the ministerial meeting. While recognizing ongoing disagreements, he remained resolute that hesitant nations would ultimately come on board.

Divisions on Timeline and Categories

The deepest rifts emerged around the proposed 2032 deadline and the classification of eligible expenditures. Some representatives, particularly from Lithuania and Estonia, criticized the timeline as insufficiently urgent. Lithuanian Defense Minister Dovile Sakaliene advocated for a 2030 target, declaring 2032 "definitely too late." Estonian Defense Minister Hanno Pevkur projected that Estonia would reach the 5 percent mark as soon as next year, urging peers to set similarly ambitious schedules.

Conversely, nations such as Spain, Germany, and Belgium voiced concerns about the practicality of the targets. Highlighting fiscal constraints and current industrial limitations, they described the 5 percent benchmark as “extremely difficult.” The United Kingdom and Italy have signaled their intent to raise core defense spending to a more modest 3.5 percent of GDP by 2035—well short of the new proposal’s expectations.

NATO data indicates progress toward existing goals: 23 out of 32 member states are expected to meet the longstanding 2-percent-of-GDP threshold by the end of this summer. Spain and Italy aim to reach that target by year-end, while Canada has projected compliance by 2027.

New Capability Targets Amid Financial Strains

In addition to budgetary debates, defense ministers approved updated capability targets designed to guarantee operational readiness and collective defense. Priorities include air and missile defense, long-range strike options, logistics, and the sustenance of large-scale land maneuver forces.

Germany underscored its commitment to NATO’s military expansion, with Defense Minister Boris Pistorius announcing plans to expand the country’s active-duty personnel by 60,000 troops. “Given Germany’s size and economic strength, we will shoulder a significant part of NATO’s military build-up,” said Pistorius. Nonetheless, he acknowledged ongoing challenges, as the Bundeswehr continues to struggle with recruitment and an increasingly aging force.

Across the alliance, tight budgets and economic headwinds present further obstacles. The Netherlands has estimated that an additional 16 to 19 billion euros—equivalent to up to 21.66 billion U.S. dollars—will be needed annually to fulfill its obligations. Dutch Defense Minister Ruben Brekelmans conveyed the steep financial climb to lawmakers, highlighting the magnitude of the task ahead.

Belgium’s Budget Minister Vincent Van Peteghem cautioned that increased defense commitments might come at the expense of social programs, emphasizing, “Every euro that’s a deficit today ... is a euro that will be debt, and that debt will be one day a tax or a cut in the social welfare state.” He insisted that balancing defense and welfare expenditures remains a paramount challenge for national governments.

As NATO members brace for further negotiations, the tension between security objectives and domestic fiscal realities is poised to dominate the agenda at the alliance’s forthcoming summit.
