The War Machine Is Being Built to Last

The IMF looked at every defense spending boom since World War II — 164 countries, data stretching back to 1946 — and found a pattern. Spending rises about 2.7 percentage points of GDP, lasts roughly three years, and leaves public debt seven points higher. Booms go bust ^[1]. What is being built now does not fit that mold. The architecture underneath the headline spending figures is designed to last decades, not budget cycles. Start with the debt instruments. The European Commission finalized a €16.68 billion loan to Romania for defense modernization and military transport infrastructure with a 45-year maturity and a 10-year grace period ^[2]. Forty-five years of debt service, locked in this summer, for a loan that explicitly blends military and civilian investment. Canada led nine allies to launch the Defence, Security and Resilience Bank, aiming to raise £100 billion — a new multinational financial institution created from scratch to channel capital toward defense production ^[3]. The UK separately launched a Multilateral Defence Mechanism for joint procurement ^[4], with both initiatives now being pushed toward merger. These are not one-off appropriations. They are standing financial infrastructure. On the legislative side, the EU reached a deal on June 10 to cut defense project permit times from up to four years to 102 working days, and extended procurement frameworks to ten years ^[5]. The Defence Readiness Omnibus, as it is called, is part of the ReArm Europe plan supporting up to €800 billion in investment over four years. The B9 and Nordic countries summit endorsed a "NATO 3.0" strategy explicitly framed as building European military capability sufficient to let the U.S. pivot to other theaters ^[6]. NATO Secretary General Rutte, who called the old model unsustainable, is demanding member states present concrete plans to reach 5% of GDP on defense by 2035 ^[7][8]. A Deloitte study projects EU defense spending to exceed 3% of GDP by 2040, up from 2.1% in 2025 ^[9]. The institutional doctrine now describes rearmament as permanent strategic realignment, not a temporary response to Ukraine. Private capital is committing to long-lived industrial capacity on the same timeline. Northrop Grumman added 20 U.S. manufacturing facilities in two years. RTX invested nearly $900 million to expand munitions production. GE Aerospace saw a 25% revenue jump in Q1 2026 ^[10]. In India, Adani Defence is investing Rs 2,500–3,000 crore to build South Asia's largest private-sector missile complex ^[11]. India's defense production hit a record $19 billion in FY26, more than doubling since FY21, with exports growing 57-fold since FY14 ^[12]. These firms are building factories, not just fulfilling orders. In the United States, the government invoked the Defense Production Act — a Cold War-era statute that lets the government direct private industry to prioritize military production ^[13] — to accelerate munitions manufacturing after the Iran war depleted stockpiles. Using a wartime emergency statute outside an officially declared war extends the tool's reach beyond the crisis that prompted it. This accompanies a Trump budget request of $1.5 trillion for FY2027, a 42% increase, while the House passed a defense authorization bill of roughly $1.14 trillion ^[14][15]. Global military spending hit a record $2.887 trillion in 2025 — the 11th consecutive annual increase ^[16]. The surge persisted even as U.S. spending declined 7.5% that year, because the rest of the world rose 9.2%. The rearmament dynamic now continues regardless of which direction American spending moves in any given year. The architecture advances. The fiscal question does not. Bulgaria faces a defense-spending demand from NATO at the same time the European Commission launched an excessive deficit procedure against it for its fiscal gap ^[17][8]. The spending targets collide directly with EU fiscal rules, and no mechanism resolves the contradiction. In the UK, military chiefs requested £28 billion but the government offered £13.5–15 billion; the National Armaments Director warned that diverting funds from other departments to close the gap would create a zero-sum game that damages economic growth ^[7]. Five NATO members — the UK, France, Spain, Italy, and Canada — blocked Rutte's proposal for a mandatory 0.25% GDP contribution to Ukraine aid, and Rutte conceded the plan would not move forward ^[18]. Only four countries — Poland, Lithuania, Latvia, and Estonia — currently meet the 5% benchmark or have credible paths to it. Spain secured a formal exemption ^[19][8]. The political articulation of the trade-off is getting blunter. Andy Burnham, positioning himself as the UK's next prime minister, proposed slashing the welfare budget to fund defense, saying the world has changed and the state must change its assumptions ^[20]. In the U.S., the proposed military budget increase would be funded through cuts to healthcare and civilian agencies as the Iran war costs over $1 billion per day ^[21].

a flat tax of 10% without a tax-free threshold leads to weaker tax progressivity — European Commission

The spending mandates are not universally accepted, the fiscal rules contradict the targets, and the political consensus to sustain the rearmament is thin outside the eastern front. But the institutional infrastructure marches forward regardless — new banks, new legislation, new factories, decades of debt. The 45-year maturity on Romania's loan and the £100 billion capital target of the new defense bank make a future pullback structurally harder to execute, regardless of whether the political will to sustain the spending survives the next recession or electoral turnover ^[2][3]. The question is not whether the infrastructure outpaces the fiscal consensus — it already has. The question is what happens when that gap becomes impossible to ignore.
