Why European Defense Stocks May Be the Trade of the Decade

The Iran war has fundamentally altered the European defense landscape. For decades, European governments systematically underfunded their militaries, relying on American security guarantees and the assumption that large-scale conflict in the modern era was a relic of the past. That assumption died on February 28, 2026.

Within weeks of the outbreak of hostilities, European nations announced a wave of defense spending increases that collectively represent the largest peacetime military buildup in the continent’s post-war history. Germany’s Zeitenwende, initially announced in 2022 after Russia’s invasion of Ukraine, has now been dramatically expanded. France, the UK, Poland, and the Nordic countries have all committed to sustained increases in military budgets.

For investors, this creates a rare and potentially transformational opportunity. European defense stocks — companies like Rheinmetall, BAE Systems, Thales, Leonardo, and Saab — are entering what may become a decade-long supercycle of revenue growth driven by government spending commitments that are politically irreversible.
