Europe's Strategic Realignment: NATO's Defense Burden Shifts East by 2027

The American National Defense Strategy of 2026 marks a fundamental turning point in the transatlantic security architecture. Washington has set a clear deadline for Europe: by 2027, NATO members in Europe are to take primary responsibility for their conventional defense. This strategic realignment, communicated by Pentagon representatives to European diplomats in Washington in December 2025, forces the continent into an accelerated military emancipation.

Under Secretary of War for Policy Elbridge Colby presented the NATO 3.0 concept at a NATO defense ministers' meeting in February 2026: Europe leads conventional defense while the United States focuses on homeland security and deterrence in the Indo-Pacific. The ideological foundation of this realignment is clearly articulated – America First, peace through strength, and the end of democratic idealism and open nation-building projects, as the strategy explicitly states.

The European response to this changed security situation is manifesting in remarkable numbers. According to the International Institute for Strategic Studies, European military spending increased by 12.6 percent in 2025 compared to the previous year, reaching a total of 326 billion euros in 2024. An additional increase of at least 100 billion euros is projected by 2027. Global defense spending reached a total of 2.63 trillion US dollars in 2025, driven by substantial increases in Europe and the Middle East.

Germany, historically cautious in defense policy matters, is making a dramatic turnaround. Berlin plans to invest around 77 billion dollars over a period of five years, which could make Germany the country with the third-largest defense budget in the world by 2030. These investments are primarily flowing into national and European programs such as the F127 frigate, the Eurofighter Tranche 5, and the IRIS-T SLM air defense system. The German realignment reflects a strategic decision to shield the domestic and European defense industry from external dependencies.

Poland has established itself as a NATO frontrunner, spending about 4.1 percent of its gross domestic product on defense in 2024, with a target of 4.7 percent for 2025. France, Italy, and the Nordic countries are also significantly increasing their spending in areas such as air defense, munitions, cyber capabilities, and naval platforms. Norway has expanded its defense plans for 2026 by an additional 2.8 percent of GDP, while the Baltic states have each increased their spending by about two percent.

The European Defence Fund will provide a total of 7.3 billion euros for defense research by 2027, supplemented by 8.8 billion euros under the European Defence Fund to promote defense research and development, as well as 1.7 billion euros to support military mobility projects through the Connecting Europe Facility. The European Commission is urging member states to complete Capability Coalitions in nine key areas: air and missile defense, strategic enablers, military mobility, artillery systems, cyber/AI/electronic warfare, missiles and munitions, drones and drone defense, land combat, and maritime capabilities.

The European defense industry faces enormous challenges. By 2030, 600,000 qualified workers will be needed, with 200,000 required by 2026. At the same time, manufacturers must demonstrate that they can ramp up production to wartime levels. McKinsey analyses show that consolidation in four key segments of the European defense industry could free up annual cost savings of about nine billion euros – more than the current defense budgets of 24 of the 30 NATO member countries in Europe.

The political implications of this development are far-reaching. The 2026 National Defense Authorization Act of the USA contains explicit protective measures for exposed allies. After the Pentagon expressed a desire to reduce support for the Baltic states, Congress added an amendment requiring the Secretary of Defense and the EUCOM commander to establish and implement a Baltic Security Initiative. This initiative aims to deepen security cooperation with the armed forces of the Baltic countries, with Estonia, Latvia, and Lithuania needing to match US investments.

A particularly concerning aspect of the current development relates to cyber defense. In March 2025, Defense Secretary Pete Hegseth ordered that US Cyber Command cease all offensive cyber operations and planning against Russia. This decision came paradoxically at a time when Russian operations against NATO allies had massively increased since the beginning of the Ukraine war. The EU military chief recently argued that the operationalization of the European Union's mutual defense clause should focus on circumstances that fall below the threshold of NATO's Article 5.

The industrial policy consequences are no less significant. While Europe absorbed 35 percent of US arms exports between 2020 and 2024 – with an import volume more than double that of the previous four years – Brussels is now seeking greater independence. The European Union has proposed an 860 billion dollar defense plan that largely excludes American contractors and prioritizes European production. Pentagon representatives, including Colby, have explicitly endorsed this development, emphasizing that the demand for defense equipment is enormous and will continue.

Defense procurement spending in the EU is expected to exceed 100 billion euros in 2025. Significant transactions in the last twelve months underscore this momentum: the German defense company Rheinmetall acquired Loc Performance Products, a US manufacturer of military vehicle components, for 950 million dollars. The American defense components manufacturer Loar Holdings purchased LMB, a French developer of fans and motors for military applications, for 365 million euros.

Analysts from Datasite predict that M&A activity in the European defense sector will increase significantly in 2026. Data from Refinitiv already shows a 35 percent year-on-year increase in M&A deal volume in the European defense sector for the first half of 2025, with a total value of 2.3 billion dollars.

The strategic transformation of Europe is taking place under significant time pressure. The 2027 deadline for taking primary responsibility for conventional NATO defense capabilities – from intelligence to missiles – has surprised some European diplomats. At the same time, it remains unclear whether Europe is actually capable of defending itself without substantial US support. Europe's capability planning – what we buy and what we develop – still derives from NATO's regional capability plans, which continue to rely on a substantial American contribution.

The coming months will show whether the European continent can meet this historic challenge or whether the rhetoric of strategic autonomy ultimately fails due to structural deficits and political fragmentation.
