Satyajit Das: The Wages of War

Key Takeaways

• Global defence spending hit $2.7 trillion in 2024
• Projected to reach $6.7 trillion by 2035
• Military share of GDP rose from 2.2% to 2.5%
• EU peace dividend valued at €4.2 trillion (~$4.9 trillion)
• Over one‑third of US defence budget spent on personnel

Summary

Satyajit Das warns that global defence spending has surged to $2.7 trillion in 2024 and is projected to hit $6.7 trillion by 2035, raising the share of GDP devoted to military budgets from 2.2% to 2.5%. He argues that modern, high‑tech weaponry offers limited spill‑over benefits and weak economic multipliers, especially for nations lacking indigenous defence industries. The piece highlights the erosion of the post‑Cold‑War peace dividend—Europe’s estimated $4.9 trillion gain over 30 years—and the growing fiscal strain on indebted governments. Das also cautions that escalating arms races and a powerful military‑industrial complex threaten both economic stability and democratic governance.

Pulse Analysis

The post‑pandemic era has seen an unprecedented acceleration in defence budgets, driven by geopolitical flashpoints and the allure of cutting‑edge weaponry. In 2024, worldwide military outlays topped $2.7 trillion, a 9.4% annual rise, and forecasts suggest they could more than double by 2035. This surge reverses the peace dividend that once freed billions for private investment and social programs, especially in Europe where a $4.9 trillion surplus was accrued over three decades. Policymakers now grapple with allocating a larger slice of GDP—up from 2.2% to 2.5%—to arms rather than growth‑enhancing sectors.

Economically, the multiplier effect of defence spending is modest. Most expenditures flow into personnel costs, pensions, and administration, with less than a third earmarked for capital investment. High‑tech systems such as the Golden Dome missile shield, projected at $500 billion to $3.6 trillion, often become obsolete before deployment, eroding value and inflating budgets. Nations lacking domestic defence bases increasingly rely on foreign suppliers, creating strategic dependencies on rare‑earths, semiconductors, and advanced engineering from the United States, Russia, China, France and Germany. Dual‑use initiatives, like Russia’s effort to repurpose war factories for civilian goods, illustrate attempts to mitigate waste, yet the overall fiscal burden remains heavy for indebted economies.

Beyond economics, expanding military capabilities fuels arms races and strengthens the military‑industrial complex, a nexus that can skew democratic decision‑making. As budgets swell, political leaders find defence spending popular, even when the public lacks nuanced understanding of its costs. The resulting escalation raises the risk of conflict, as history shows with the Thucydides trap, while diverting talent and capital from innovation that could sustain long‑term prosperity. A balanced approach—prioritising diplomatic solutions, investing in dual‑use technologies, and scrutinising procurement—offers a pathway to curb the fiscal and security risks of unchecked militarisation.
