Rutte Sells Trump on 5% Defence

Mark Rutte went to Washington this week with a delicate job: keep Donald Trump from using next month’s Ankara summit as a televised reckoning over European free-riding. Over three days, the NATO secretary general met Trump, senior officials and members of Congress (NATO). The pitch was blunt enough for its audience: European spending is rising, and allies have heard the complaint (Euronews, KSAT).

The difficulty is that NATO’s new target works better as politics than as military planning. Trump can see a large number. European capitals can point to movement. But the alliance still has no settled answer on what counts, who fills the most serious capability gaps, or what happens when governments miss the mark.

A Target That Invites Creative Accounting

The promise Rutte is selling is the one allies signed at NATO’s Hague summit: 5% of GDP on defence and defence-related spending by 2035. It is split into 3.5% for core military needs and 1.5% for a wider basket covering infrastructure, cyber resilience, civil preparedness and defence industry (NATO, BBC). That second category is where the trouble starts. A government can present railway upgrades, port repairs or disaster-response budgets as defence contributions without buying a missile.

The broad numbers are still meaningful. Rutte said after the ministerial meetings that European allies and Canada increased core defence investment by more than $90 billion in real terms in 2025 (NATO). All 32 allies now meet the older 2% benchmark (Atlantic Council). But Rutte has also warned that "cash alone does not stop missiles or tanks", and that Ankara has to produce deployable capability rather than tidy budget lines (NATO).

For Irish readers, the point matters even outside NATO. Ireland’s neutrality keeps it out of the alliance, but EU defence debates are increasingly shaped by the same question: whether European countries are building real capacity or simply moving public spending into more convenient columns.

Spain shows the definition problem neatly. Madrid says it can meet capability objectives at roughly 2.1% and wants cyber, telecoms and disaster-response spending counted inside the resilience basket (Index.hr). According to the Brussels Times, it was the only ally that did not sign the Hague 5% pledge (Brussels Times). If that logic spreads, the target becomes a set of national accounting choices rather than a common military standard.

Germany is the other side of the same argument. Berlin says its role as NATO’s logistical backbone means roads, bridges and ports are genuine defence investments, under the idea it calls "Gesamtverteidigung", or total defence (BMVg). There is a real military case here: reinforcements heading east would move through German infrastructure. There is also a budgetary convenience for a government facing a €42 billion financing gap and auditor warnings about procurement waste as spending rises (Tagesschau).

The Capability Gap Behind the Numbers

Rutte’s urgency has a practical source. The United States is reviewing its force posture in Europe, and Rutte acknowledged that Washington was adjusting contributions to NATO’s Force Model, the alliance’s blueprint for which countries provide which units and assets. He said allies were being asked to cover some of the gaps (NATO). If US air defence, intelligence, logistics and command assets shift towards the Indo-Pacific, Europe either replaces them or accepts weaker deterrence along NATO’s eastern border with Russia.

Italy then showed a different meaning of burden-sharing. After Rutte said about 500 US aircraft had departed from Italy to support operations against Iran, Defence Minister Guido Crosetto insisted Rome had authorised only technical and logistical flights, not combat missions. He offered to report to parliament flight by flight (Open, Adnkronos). Opposition parties demanded to know whether Italian territory had been used for strikes without parliament knowing (Il Fatto Quotidiano).

That episode is still unresolved. It also exposes what spending pledges leave out. Bases, overflight and logistics can pull a country into US operations before voters have any clear account of what their government has allowed.

No Penalty for Missing the Target

Rutte’s Washington trip bought time. It did not settle the argument. NATO has no mechanism to fine or sanction allies that miss the 5% target; this is a summit pledge, not a treaty clause with enforcement behind it (Defence Priorities). Nor is there an agreed line-by-line definition of what belongs inside the 1.5% resilience basket, leaving governments room to count roads, ports, cyber programmes or civil-preparedness budgets as defence (NATO Association of Canada).

Rutte can manage Trump for a summit cycle. Turning 32 countries’ budget promises into units, stockpiles and logistics that exist before a crisis is a much harder job, and no NATO secretary general can do it by persuasion alone.
