Mercenaries Made in Europe? Exploring the Need for a European Regulatory Framework of Private Military Companies

This research paper examines the operations of European Private Military Companies (PMCs) and their implications for European security, both abroad and domestically. It discusses two case studies on European-based PMCs which were involved in an incident in the eastern Congolese city of Goma after Rwandan-backed rebels captured the town in January 2025. The study finds significant potential risks to European foreign policy and security interests arising from European military contractors’ collaboration with strategic contestants of Europe and their operational conduct in conflict areas. Additionally, it reveals how European PMCs operating in third countries can be linked to ventures that undermine security within Europe, as demonstrated in the case of Romania, highlighting the dangers posed by inadequate control mechanisms of European-based military contractors. The analysis concludes with policy recommendations for a unified European regulatory mechanism to oversee PMCs.

Hope For a New Perspective on Ballistic Missile Non-Proliferation? An Analysis of International Humanitarian & Environmental Law and Political Science

This paper explores the persistent dangers of ballistic missiles (BMs) despite international legal efforts to curb their proliferation and use. It analyses violations of International Humanitarian Law (IHL) and International Environmental Law (IEL), using the 44-Day War between Armenia and Azerbaijan as a case study to illustrate the devastating impact of BMs on civilians and the environment. While acknowledging the challenges posed by realist perspectives in international relations, the paper adopts a constructivist approach, suggesting that a shift in state identities and interests could encourage greater commitment to disarmament efforts. In this regard, the EU Space Strategy is highlighted as a potential avenue for promoting norms that prioritise humanitarian and environmental concerns in the context of space security.

From Resilience to Deterrence: Is the EU Shifting Toward Proactive Cyber Defence?

This paper examines the European Union’s evolving cyber defence strategy in response to the growing integration of cyber operations into hybrid warfare. It traces the EU’s doctrinal shift from a reactive, resilience-based posture to one that increasingly embraces proactive deterrence, including the potential use of offensive capabilities. By analysing key strategic documents and highlighting the case of France, the study illustrates both progress and limitations. While conceptual advances are evident, practical implementation remains a national competence. The paper concludes that translating strategic ambition into credible cyber deterrence will require legal clarity, interoperability, and coordinated capability development.

The Importance of Electronic Warfare for European Land Forces: Lessons from the War in Ukraine

Armed forces in all domains are becoming increasingly reliant on electronic equipment that uses the electromagnetic spectrum (EMS) and its associated frequencies. Electronic warfare (EW) serves both to secure and to deny access to the EMS. The war in Ukraine had demonstrated that EW capabilities are now crucial for land forces, with their scope and applications continuously expanding. For example, unmanned aerial vehicles (UAVs) have become the focus of a contest in EW between Ukraine and Russia, with each side attempting to deny the other the use of these systems and the EMS necessary for their operation. European land forces should observe and assimilate the lessons from Ukraine’s experience in EW, as their own EW capabilities have become largely obsolete or insufficient.

A Legal Analysis of Space Debris I: The Kessler Syndrome and the Regulation of Space in International Law

The evolution of industrial models applied to space technologies has opened the door to space exploration and activities for smaller states and private actors. This proliferation of actors and the access to launching objects into Earth’s orbit has multiplied the amount of functional and non-functional objects in space, increasing the amount of space debris and the risk of triggering the Kessler Syndrome. This paper is the first of a series of articles analysing this challenge from a legal perspective. In this first part, the purpose is to frame the space debris threat and analyse the regulation of space in International Law.
