The push for increased military spending across Europe, spurred in part by former U.S. President Donald Trump’s unpredictable foreign policy and, more recently, his renewed questioning of NATO commitments, is facing a critical, yet largely overlooked, challenge: antitrust regulations. Whereas European nations scramble to rearm and bolster their defense industries, existing competition laws may significantly hinder the speed and scale of necessary consolidation and collaboration, potentially leaving the continent vulnerable.
Trump’s repeated criticisms of European defense spending, and his surprising interest in acquiring Greenland – a strategically located territory with implications for missile defense and Arctic control – served as a wake-up call for many European leaders. As the BBC reported in January 2026, Trump insisted he was seeking “immediate negotiations” to acquire Greenland for national security reasons, even stating he “won’t use force.” This demand, though ultimately softened after discussions with NATO Secretary General Mark Rutte, highlighted a perceived lack of reliability in U.S. Security guarantees and prompted a reassessment of European defense capabilities.
The current geopolitical landscape, further complicated by the ongoing conflict in Ukraine, has intensified this rearmament zeal. However, the structure of the European defense industry – characterized by numerous national champions and a fragmented market – presents a significant obstacle. To achieve the necessary economies of scale and technological advancements, consolidation through mergers and acquisitions is widely seen as essential. But such moves are likely to run afoul of the European Commission’s Directorate-General for Competition, which enforces antitrust rules.
The Antitrust Hurdle
The core issue is that merging defense companies, even if strategically justified, could lead to monopolies or oligopolies, potentially raising prices and stifling innovation. The European Commission is tasked with preventing such outcomes, and its scrutiny of defense mergers is notoriously rigorous. This creates a paradox: the demand for rapid rearmament clashes with the legal framework designed to ensure fair competition. As Reuters Breakingviews points out, Trump’s actions have accelerated the rearmament push, but the antitrust blind spot could undermine its effectiveness.
The situation is particularly acute in areas like ammunition production, where Europe faces critical shortages. Increasing capacity requires significant investment and streamlined production processes, which are more easily achieved through consolidation. However, even seemingly uncontroversial mergers could face lengthy investigations and potential roadblocks from competition authorities. The “Greenland crisis”, as it has been termed, has underscored the urgency of bolstering European defense capabilities, but the regulatory environment remains a significant impediment.
Beyond Mergers: Collaboration and Joint Procurement
The challenge extends beyond mergers and acquisitions. Even collaborative projects, such as joint procurement of weapons systems, can raise antitrust concerns if they involve information sharing or coordinated bidding practices. While the European Commission has acknowledged the need for greater defense cooperation, it has yet to fully address the inherent tensions between competition law and security imperatives.
Some argue for a more flexible approach to antitrust enforcement in the defense sector, allowing for a degree of consolidation that would otherwise be prohibited. Others propose creating a dedicated regulatory framework specifically tailored to the unique needs of the defense industry. However, any such changes would require careful consideration to avoid undermining the principles of fair competition and transparency.
The U.S. Example and European Sovereignty
The United States, by contrast, operates under a different set of rules. The U.S. Department of Justice and the Federal Trade Commission have greater leeway to consider national security concerns when reviewing mergers and acquisitions, particularly in the defense sector. This allows for faster consolidation and a more streamlined approach to building up defense capabilities.
The discrepancy highlights a broader debate about European strategic autonomy and the need to reduce reliance on the United States. As Europe seeks to assert its independence on the world stage, it must likewise address the structural impediments that hinder its ability to defend its interests. The push for rearmament is a crucial step in this direction, but it will only succeed if policymakers can find a way to navigate the complex landscape of antitrust regulations.
Recent developments, as reported by The Japan Times, indicate that Europe is increasingly focused on reducing its dependence on U.S. Defense. This trend is likely to intensify as geopolitical tensions continue to rise.
What’s Next?
The European Commission is expected to release a novel defense industrial strategy in the coming months, outlining its vision for the future of the European defense industry. This strategy will likely address the antitrust challenges and propose potential solutions. However, the details remain uncertain, and the implementation of any new policies will require the support of member states. The next key checkpoint will be the publication of this strategy, anticipated before the end of the second quarter of 2026.
The debate over Europe’s rearmament zeal and its antitrust blind spot is far from over. It is a complex issue with no easy answers. But one thing is clear: Europe must find a way to reconcile its commitment to competition with its need for security if it is to effectively defend its interests in an increasingly uncertain world.
