NATO member states are discussing a new defense spending target of five percent of each member's gross domestic product [1].
The proposal represents a significant escalation in military investment across the alliance. This shift follows direct demands from U.S. President Donald Trump for allies to increase their financial contributions to strengthen collective security [1, 2].
During the 36th NATO Heads of State and Government Summit held in June 2026 [3], leaders met in The Hague and Ankara to coordinate the plan. The strategy involves a phased increase in military purchases and budget allocations. While the target is being endorsed now, the alliance aims for full compliance by 2035 [4].
Support for the measure is widespread among the alliance. "Most U.S. allies at NATO endorse President Donald Trump’s demand that they invest 5% of gross domestic product on their defense needs," the Associated Press said [1].
However, the agreement faces internal friction. Reports indicate that Spain is considering opting out of the target, which some observers said could risk derailing the summit's objectives [5].
Despite these contradictions, the general trajectory of the alliance is toward higher spending. Reuters said NATO leaders were expected to endorse the target at the summit in The Hague as demanded by the U.S. president [2]. The discussions included high-level officials such as the Netherlands' Mark Rutte and Turkey's Vice President Cevdet Yılmaz.
This movement toward a five percent threshold marks a departure from previous spending guidelines. The transition requires member states to overhaul their national budgets to accommodate the increased military costs over the next decade [4].
“Most U.S. allies at NATO endorse President Donald Trump’s demand that they invest 5% of gross domestic product on their defense needs.”
The shift to a 5% GDP spending target signals a fundamental change in the NATO burden-sharing model. By anchoring the target to a specific percentage of economic output and setting a 2035 deadline, the alliance is attempting to institutionalize US demands for increased European military autonomy and financial contribution. The tension between broad endorsement and specific holdouts like Spain highlights the difficulty of aligning diverse national economies under a single, aggressive security mandate.
