NATO's 5% Target Is Already Agreed — The Real Fight Is How (and Whether) the U.S. Implements It
At the June 2025 Hague Summit, all 32 NATO allies except Spain — which received an explicit exemption — committed politically to spending 5% of GDP on defense by 2035 (3.5% on core defense). The credible danger is not renegotiating the number but the Trump administration weaponizing it: treating the target as a unilateral litmus test tied to threats of withdrawing Article 5 guarantees, intelligence cuts, or troop reductions — a direct threat to collective defense and constitutional governance. The progressive alternative must codify the Hague commitments into a phased, accountable framework that preserves alliance trust, avoids punishing allies like Spain for their legitimate exceptions, and advances the European strategic autonomy Walt recommends over a five- to ten-year timeline.
The 5% NATO defense spending target is no longer a proposal — it is a binding commitment. At the June 2025 Hague Summit, all 32 allies except Spain (which received an explicit exemption) agreed to allocate at least 3.5% of GDP to core defense by 2035, with the full 5% target encompassing broader security investments (NATO official text, AP, Reuters). Spain reached a separate agreement with NATO to aim for 2.1% of GDP, acknowledging its unique fiscal and geographic constraints (La Moncloa, Reuters). The target is locked in. The question now is whether the United States treats it as a collective milestone to be phased in with transparency and burden-sharing — or as a weapon to threaten allies with withdrawal of security guarantees, intelligence-sharing cuts, or troop reductions.
According to Stephen Walt, Europe should become more responsible for its own defense, but the transition should be gradual — over five to ten years — so that Europe can build its own security institutions and the U.S. can count on its diplomatic support. The Trump administration's pattern of 'burning up the alliance' risks giving allies incentives to form coalitions against the U.S. or to reach out to other powers (NPR, Feb 2025). The progressive path is not to fight the 5% target, which is already agreed, but to fight the implementation: codify the Hague targets into a phased, accountable framework with clear benchmarks, protect the Spanish exemption as a precedent for flexibility, restore intelligence-sharing and joint planning channels, and embed the target within a framework of European strategic autonomy — not U.S. unilateral coercion.
The humanitarian alternative
A humanitarian and strategic alternative would be a comprehensive U.S.-Europe-Ukraine defense compact that phases in European military autonomy over five years while immediately restoring full U.S. support for Ukraine's air defense and logistics. This would include a $40 billion supplemental package (funded by closing corporate tax loopholes), a binding NATO commitment to spend 2.5% of GDP on collective defense by 2028, and a standing joint command structure that includes Ukraine as a non-voting partner. Such a framework would reduce long-term U.S. troop presence, strengthen European defense industrial capacity (including joint production of 155mm shells and drones with Ukraine), and ensure no single nation—whether the U.S. or Ukraine—bears the full cost of deterrence.
Falsifiable predictions
What this entry claims will happen, and what data would prove it wrong. The Reckoner revisits these against current reality.
- At the Ankara summit, NATO will fail to agree on a unified defense spending target above 2% of GDP, with multiple members refusing to meet the 3.5% demand.
- The U.S. will not sign a new multi-year security assistance package for Ukraine before the summit, leading to a further degradation of Ukraine's air defense capabilities within 90 days.
