Europe's Defense Shift: Between NATO Objectives and Industrial Reality

The European defense landscape is undergoing a historic transformation in March 2026. Following the NATO summit in The Hague in June 2025, alliance partners face the greatest rearmament challenge since the end of the Cold War. The new spending target of 5 percent of gross domestic product – divided into 3.5 percent for core defense and 1.5 percent for defense-related infrastructure and resilience measures – marks a paradigm shift in European security policy.

The magnitude of this commitment becomes clear only in comparison: While the Wales summit in 2014 agreed on just 2 percent, the new target represents more than a doubling of defense spending within a decade. According to current NATO estimates, by 2025, all member states except Iceland will reach the old 2 percent mark for the first time. Five countries – Denmark, Estonia, Latvia, Norway, and the USA – are already exceeding the 3 percent threshold, while Lithuania and Poland are investing more than 4 percent. Notably, all NATO members except Belgium also meet the 20 percent target for equipment investments.

The driving force behind this development is undoubtedly the Russian threat and the resulting regional defense plans of NATO from 2023. However, the massive increase in spending is also a response to the repeated demands of the Trump administration for Europe to take more responsibility for its own security. The figures show that Europe is indeed catching up: While NATO Europe and Canada accounted for only 28 percent of total alliance spending in 2015, this share has risen to 36 percent by 2024 and is expected to reach 38 percent in 2025.

Nevertheless, data from the International Centre for Defence and Security reveal a significant implementation problem. Currently, 16 of the 32 alliance partners – exactly half – are just above the 2 percent threshold, with spending between 2.0 and 2.1 percent of GDP. Only three countries – Latvia, Lithuania, and Poland – have already reached the new 3.5 percent target. Most allies have yet to present concrete roadmaps on how they plan to meet the ambitious targets by 2035.

However, it is worth highlighting the accelerated timelines of individual states: Italy plans to reach the 2 percent target three years earlier than originally intended, Spain five years earlier, and Belgium even ten years earlier. Other countries have maintained their original timelines but have massively increased their planned spending. Norway, for example, has increased its budget for 2026 by an additional 2.8 percent of GDP, Poland by 2.0 percent, and the Baltic states by around 2 percent each.

In absolute terms, this development represents a significant leap: The defense budgets of EU member states rose from 218 billion euros in 2021 to 326 billion euros in 2024. By 2027, another increase of at least 100 billion euros is projected. Globally, defense spending is expected to reach 2.63 trillion US dollars in 2025, according to the International Institute for Strategic Studies, an increase from 2.48 trillion US dollars the previous year. In real terms, this corresponds to an increase of 2.5 percent, driven particularly by Europe and the Middle East.

The European Commission has responded to this challenge with the "Defence Readiness Roadmap 2030," a comprehensive plan to close critical capability gaps. The document defines four strategic flagship initiatives: the European Drone Defence Initiative, the Eastern Flank Watch, the European Air Shield, and the European Space Shield. These initiatives aim to strengthen Europe’s ability to deter and defend across land, air, sea, cyberspace, and outer space, directly contributing to NATO capability goals.

Particularly noteworthy is the approach of "Capability Coalitions" in nine key areas: air and missile defense, strategic enablers, military mobility, artillery systems, cyber warfare with AI and electronic warfare, missiles and munitions, drones and drone defense, land combat, and maritime capabilities. Member states are expected to address these gaps through joint development and procurement.

The European Defence Fund will provide a total of 8.8 billion euros for research and development by 2030, while 1.7 billion euros from the Connecting Europe Facility are earmarked for military mobility projects. A particular focus is on creating a unified EU defense market with common rules, enabling the industry to produce faster and on a larger scale.

The industrial dimension of this rearmament should not be underestimated. Europe must transform its defense industry not only quantitatively but also qualitatively. The Commission plans to monitor industrial capacities, starting with air and missile defense, drones, and space systems. At the same time, the resilience of supply chains will be strengthened by reducing critical dependencies on raw materials and other essential inputs.

Another focus is military mobility. By 2027, a Europe-wide mobility area with harmonized rules and a network of land, air, and sea connections is to be established, enabling rapid troop transport across Europe. This initiative has been developed in close coordination with NATO and is expected to significantly improve Europe’s responsiveness in crises.

The economic impact of these massive defense expenditures is being debated controversially. Economists expect a moderate growth impulse but warn against overblown expectations. Goldman Sachs analysts point out that national debts combined with the repurposing of unspent EU funds could finance military expenditures until 2026. However, long-term structural barriers remain: long production lead times, a shortage of skilled workers, and limited industrial capacities could restrict the economic benefits.

The European Commission forecasts defense spending of 1.6 percent of GDP for 2026 – an increase from 1.3 percent in 2023. However, this is still well below NATO target guidelines and highlights the gap between political declarations of intent and budgetary realities in many member states.

The central question remains: Will Europe keep its promises? The history of the Wales Pledge from 2014 teaches that political commitments are difficult to enforce without sanction mechanisms. The new ten-year plan until 2035 – a compromise, as several allies demanded a faster implementation – offers grounds for cautious optimism. The massive budget increases of the last three years and the accelerated timelines of many countries suggest that Europe is serious this time.

What will be crucial is whether European states not only spend more money but also invest more efficiently. Joint procurement, standardization, and industrial consolidation are essential to generate maximum defense capability from every euro invested. The Capability Coalitions could bring about a breakthrough here – provided that national egoisms give way to European solutions.

The geopolitical reality leaves Europe with no choice. With a resurgent Russia on the eastern flank, an uncertain transatlantic partnership, and growing global tensions, the continent must take its defense into its own hands. The figures show: The process has begun. Whether it progresses quickly and decisively enough will determine Europe’s security and strategic autonomy in the coming decades.
