NATO’s Bold New Defense Spending Pledge: A 5% GDP Target Amid Global Tensions

In a landmark decision at the NATO summit held in The Hague on June 24-25, 2025, the alliance’s 32 member states agreed to a significant escalation in defense spending, setting a new target of 5% of each nation’s gross domestic product (GDP) by 2035. This agreement marks a dramatic shift from the previous 2% GDP guideline established in 2014, reflecting heightened concerns over global security threats, particularly from Russia, and pressure from the United States to redistribute the financial burden of collective defense.
The summit, attended by heads of state and government, including U.S. President Donald Trump, also addressed critical issues such as support for Ukraine, defense production, and strategic alignment in a rapidly changing geopolitical landscape.

The new 5% GDP target breaks down into 3.5% allocated to “hard defense” expenditures—such as weapons, troops, and military operations—and an additional 1.5% for defense-related investments, including cybersecurity, military mobility infrastructure, and technology development. This broader definition of defense spending allows flexibility for member states to include non-traditional security measures, such as upgrading rail lines and bridges to support military convoys or enhancing intelligence capabilities. The agreement also permits contributions to Ukraine’s defense to count toward the 5% goal, a provision aimed at aligning the alliance’s priorities with ongoing support for Kyiv against Russia’s aggression.

The road to this agreement was not without friction. Spain emerged as a significant holdout, with Prime Minister Pedro Sánchez initially labeling the 5% target “disproportionate and unnecessary.” Spain, which spent only 1.24% of its GDP on defense in 2024, argued that meeting the new goal would require drastic cuts to social programs or unsustainable tax hikes. After intense negotiations, NATO leaders crafted a compromise, adjusting the summit statement’s language from “we commit” to “allies commit,” granting Spain flexibility to determine its own path toward meeting the alliance’s capability targets. Sánchez claimed Spain could fulfill its obligations by spending 2.1% of GDP, leveraging its domestic defense industry to reduce costs. This concession sparked criticism from Poland, which warned that Spain’s exemption could undermine NATO unity, and Belgium, which also sought similar flexibility.
The push for higher defense spending has been a long-standing demand from the United States, amplified by President Trump’s vocal insistence that European allies shoulder more of the alliance’s costs. The U.S., currently spending approximately 3.2-3.4% of its GDP on defense, has historically accounted for nearly two-thirds of NATO’s total defense expenditures. Trump’s pressure, coupled with NATO Secretary General Mark Rutte’s diplomatic efforts, culminated in the new pledge. Rutte, who met with Trump multiple times since his re-election in November 2024, emphasized the urgency of increased investment, citing intelligence reports that Russia could pose a direct threat to the alliance within three to five years. The agreement includes a review of the spending trajectory in 2029, allowing for adjustments based on economic and security developments.
Beyond the spending target, the summit addressed other critical priorities. NATO leaders reaffirmed their “ironclad commitment” to collective defense under Article 5, despite Trump’s ambiguous remarks about the mutual defense clause, where he suggested its application might depend on interpretation. The alliance also focused on ramping up defense production to address capability gaps, particularly in air defense systems, long-range missiles, fighter jets, tanks, and drones. This push for industrial capacity aims to reduce reliance on U.S. weapons systems and bolster Europe’s defense industry, though concerns remain about the feasibility of rapid scaling amid economic constraints in countries like France, Germany, and the United Kingdom.
Support for Ukraine remained a central theme, with NATO officials emphasizing that aid to Kyiv could count toward the 5% GDP target. This provision reflects the alliance’s ongoing commitment to countering Russia’s invasion, now in its third year, while balancing concerns about diverting focus to other global crises, such as tensions in the Middle East. The summit also saw discussions on reducing defense trade barriers, aiming to streamline procurement and enhance interoperability among member states’ forces.
The 5% target represents a formidable challenge for many NATO members. In 2024, 23 of the 32 allies met or exceeded the 2% GDP guideline, a significant improvement from just three in 2014. Poland leads the alliance, spending 4.7% of its GDP on defense, driven by its proximity to Russia and fears of escalation. Baltic states like Estonia and Lithuania, both planning to hit 5% by 2026, have adopted a “porcupine” strategy, prioritizing small, mobile, and lethal weapons to deter potential Russian aggression. Greece, spending over 3%, and the U.S. at 3.4%, also rank among the top spenders. However, major economies like Canada (1.3%), Italy (1.5%), and Portugal (1.5%) lag behind, facing domestic economic pressures that complicate meeting the new goal.
Critics argue that the 5% target risks sparking an arms race with adversaries like Russia or China, potentially destabilizing global security. Others question its economic feasibility, particularly for nations with high budget deficits or competing domestic priorities. European arms manufacturers stand to benefit, but the emphasis on U.S.-made weapons could limit domestic economic gains in Europe. Despite these concerns, NATO’s commitment reflects a recognition that the security environment has fundamentally changed since Russia’s 2022 invasion of Ukraine, necessitating a robust and unified response.
The Hague summit has set NATO on a path toward unprecedented defense investment, signaling a new era of burden-sharing and strategic preparedness. Whether all members can meet the ambitious 2035 deadline remains uncertain, but the agreement underscores the alliance’s resolve to confront emerging threats while navigating internal divisions and external pressures. As the world watches, NATO’s ability to translate pledges into concrete capabilities will determine its effectiveness in safeguarding the Euro-Atlantic area for years to come.
