Europe's Armament: 800 Billion Euros and the End of Pacifism

The European Union is facing the largest military buildup since the end of the Cold War. With the "Defence Readiness Omnibus" adopted on June 17, 2025, and the overarching plan "REarm Europe/Readiness 2030," EU member states are mobilizing a total of 800 billion euros for defense spending over the next four years. This historic turning point marks the end of an era in which Europe relied on the security umbrella of the United States and pursued extensive demilitarization.

Defense spending by EU member states has already increased from 218 billion euros in 2021 to 381 billion euros in 2025—a rise of 75 percent within just four years. According to the International Institute for Strategic Studies (IISS), this means that about 21 percent of global military spending is now accounted for by Europe. The new target aims for member states to increase their defense spending from an average of 1.9 percent of GDP in 2024 to 3.5 percent by 2030. Germany, long criticized for its restrained defense policy, plans to spend 162 billion euros by 2029—about 3.5 percent of its gross domestic product. This will make Germany the largest defense budget in Europe.

This drastic turnaround is driven by two central factors: first, the fear of an expansive Russia following its invasion of Ukraine on February 24, 2022, and second, growing doubts about the reliability of American security guarantees under a potentially more isolationist U.S. administration. What began as an emergency response to the Ukraine war has evolved into a structural realignment of the European security architecture.

The plan presented by EU Commission President Ursula von der Leyen includes several key elements. The 150 billion euro loan program "SAFE" (Security Action for Europe) is intended to support joint arms procurement, with a fundamental rule that no more than 35 percent of component costs may come from outside the EU, the EEA-EFTA states, or Ukraine. Additionally, one billion euros will be allocated in 2026 for the European Defense Fund, primarily for research and development in the areas of hypersonic missile defense, drone swarms, and next-generation tanks.

Particularly noteworthy is the activation of the so-called "national escape clause" in the Stability and Growth Pact, which allows member states to spend an additional 1.5 percent of GDP on defense without violating EU budget rules. This measure enables a massive expansion of military spending without national governments having to fear sanctions from Brussels.

The European arms industry is experiencing an unprecedented boom. Rheinmetall CEO Armin Papperger told Reuters: "A new era of rearmament has begun in Europe." The Europe's Aerospace and Defence Index has risen sharply over the past year. Fitch Ratings estimates that the eight largest defense companies will see at least 15 percent demand growth compared to 2024, with a combined cash flow of record-breaking 8 billion euros. Rheinmetall is acquiring the U.S. supplier Loc Performance Products for 950 million dollars, while the French company Safran is purchasing the AI defense company Preligens for around 220 million euros.

Even start-ups are benefiting from the arms boom. The European company Helsing is raising 600 million euros in a Series D funding round for AI-driven drone and electronic warfare systems. The investment industry has reclassified defense as a "public good," comparable to environmental protection, allowing institutional investors to build ESG-compliant portfolios with defense stocks.

However, the path to military independence is fraught with significant challenges. Despite the massive financial injections, European factories cannot ramp up production capacities overnight. Bottlenecks in supply chains and limited production capacities are slowing down the transformation. Ukraine urgently needs ammunition and drones, but the full production capacity of projects funded by the European Defense Fund will not be reached until the early 2030s. Therefore, Europe is temporarily purchasing off-the-shelf systems while simultaneously building and scaling its own production lines.

The economic implications are contentious. Filippo Taddei, chief Europe economist at Goldman Sachs, argues that increased defense spending will support European growth, particularly in the pressured industrial sector. Carsten Brzeski, global macro chief at ING, warns of a "negative multiplier effect on growth" in the short term. Klaas Knot, president of the Dutch central bank, believes a temporary fiscal exception for higher defense spending is justified but warns that public debt in the EU remains excessively high.

A central dilemma lies in the unequal distribution of burdens within the bloc. Wealthy nations like Germany and the Netherlands can borrow cheaply and invest aggressively in arms production, while poorer states in Eastern and Southern Europe risk over-indebtedness or falling behind the pace of their richer counterparts. This asymmetry could lead to political tensions within the Union and test the solidarity of the alliance.

Ethical questions are also at stake. Europe has long positioned itself as the most ethical society in the world. The repositioning of defense as an ESG-compliant investment is controversial, especially in light of existing arms exports to Saudi Arabia and Israel. Concerns about dual-use technologies that could later be exported to countries with questionable human rights records remain a sensitive point in public debate.

In parallel with the EU initiative, the United Kingdom, Finland, and the Netherlands announced a trilateral partnership for joint procurement of weapons and military material on March 17, 2026. This cooperation, which aims for initial concrete procurements by 2027, seeks to reduce costs through scaling and improve supply security. Particularly noteworthy is a deepened UK-Ukrainian drone alliance that combines advanced Ukrainian drone technology with British manufacturing capacity to jointly develop, produce, and export systems.

Europe has recognized that pacifism and external security umbrellas are no longer sufficient in an increasingly unstable world. The wars in Ukraine and the geopolitical tensions in the Middle East have ended an era in which many Europeans believed that large-scale wars on the continent were a thing of the past. The coming years will show whether the Union can not only mobilize the money but also master the industrial, political, and societal challenges that accompany this historic transformation. Germany and Europe are rearming—the question now is whether they will also be ready for action in time.
