Diplomatic Compass · Edition No. 1 · 8 December 2025 · By Hafsa M. Temsamani, PhD
Editorial
Welcome to the first newsletter of Diplomatic Compass. With this launch, I aim to offer clear, focused, and timely analysis on NATO affairs, Euro-Atlantic security, NATO–EU cooperation, and the Southern Neighbourhood partnerships.
From Brussels, I follow the strategic debates, ministerials, summits, and policy shifts that shape Europe’s security environment. This newsletter brings those developments into sharp relief — with concise insights, diplomatic perspective, and an analytical lens rooted in more than a decade of work inside the Euro-Atlantic system.
Diplomatic Compass begins with one purpose: to provide professionals and policymakers with accessible, relevant commentary that cuts through noise and highlights what truly matters for Europe’s security.
I. NATO Affairs
NATO December Ministerial: Key Signals on the Road to Ankara 2026
The December Foreign Ministers’ meeting in Brussels delivered a clear strategic message: NATO is accelerating implementation of decisions taken at the 2025 Hague Summit, with a sharpened focus on deterrence, capability delivery, and sustained support to Ukraine. As global competition deepens, ministers used the meeting to underline that Europe must assume greater strategic responsibility within the Alliance.
Two developments stood out. First, Allies reviewed progress on the 5% defence investment trajectory, shifting emphasis from budget announcements to real outputs: air and missile defence, mobility, readiness, sustainable ammunition stockpiles, and industrial expansion. Second, the meeting highlighted Europe’s growing responsibility as the United States adopted a more selective diplomatic posture.
In parallel, Kaja Kallas, EU High Representative for Foreign Affairs and Security Policy, attended the NATO–Ukraine Council, underscoring that Ukraine remains the centre of gravity of Allied strategy and that its security is inseparable from NATO’s own.
Key Takeaways
- Investment becomes capability: The 5% trajectory moves from pledge to implementation, with increased pressure on readiness, mobility, and defence-industrial production.
- Ukraine support remains central: Contributions to the Prioritised Ukraine Requirements List exceeded USD 4 billion, reinforcing long-term commitment through the NATO–Ukraine Council.
- Strategic momentum toward Ankara: The 2026 Summit will require decisions on force posture, industrial scaling, mobility targets, and burden-sharing models.

II. Euro-Atlantic Security
Hybrid Airspace Incidents in Belgium: What the Drone Alerts Reveal About Europe’s Vulnerabilities
A series of recent drone alerts over Belgian airspace — including near Kleine-Brogel Air Base and civilian airports — exposed vulnerabilities in Europe’s hybrid-threat posture. The incidents highlighted gaps in air-domain awareness, civil–military coordination, and crisis communication at a time when adversaries increasingly use low-cost technologies to test institutional readiness. The events also underline a broader Euro-Atlantic reality: hybrid probing no longer targets borders — it targets governance systems, exploiting slow coordination, fragmented responsibilities, and the cognitive space where speculation spreads faster than facts.
Key Takeaways
- Hybrid tools exploit ambiguity: Low-cost drones can test detection networks, reaction times and communication chains without crossing the threshold of armed conflict.
- Belgium as a strategic testbed: Hosting NATO HQ, SHAPE and EU institutions makes Belgium a prime site for hybrid observation and signalling.
- Civil–military coordination remains uneven: The incidents revealed the need for faster data-sharing between Defence, Interior, intelligence, police and aviation authorities.
- EU and NATO interdependence grows: Hybrid airspace activity in Belgium affects both EU institutional security and NATO’s situational awareness framework.
- The cognitive front matters: Social-media speculation amplified uncertainty — reinforcing the need for faster, coherent, transparent public communication.

III. NATO–EU Cooperation
President Trump’s National Security Strategy: Implications for Europe and NATO
The November 2025 U.S. National Security Strategy (NSS) sets a decisive shift in American foreign-policy thinking: the post–Cold War era is officially over. The document articulates a tighter hierarchy of U.S. interests, centred on homeland protection, strategic industries, and selective engagement abroad—an approach rooted in national resilience rather than global ambition.
The NSS is explicit about what U.S. strategy is not: it rejects the assumption that America will indefinitely underwrite the entire international order. In one striking line, the NSS states that “the days of the United States propping up the world order like Atlas are over.” For Europe and NATO, the strategic message is unambiguous: European Allies must assume far greater responsibility for capability generation, defence investment, industrial output, and resilience.
Europe’s Capability Responsibility: Washington’s focus on domestic resilience and industrial strength increases expectations on European NATO Allies to:
- close long-standing capability gaps,
- enhance deployability and readiness,
- strengthen mobility and logistics, and
- deliver sustained contributions to NATO’s deterrence and defence posture.
The NSS does not impose new numerical targets, but it sets a clear political baseline: European Allies must contribute real capability outputs, not only financial pledges.
Industrial Capacity and Defence Production: Industrial resilience is a core theme. The NSS emphasises:
- secure supply chains,
- technology leadership,
- production capacity for sustained operations, and
- access to critical materials.
For Europe, this reinforces the urgency of accelerating defence-industrial performance and aligning with NATO requirements. The logic is clear: industrial strength is now a pillar of deterrence, not a supporting function.
Strategic Competition with China: The NSS frames competition with China as a defining structural reality, highlighting:
- critical infrastructure protection,
- technology standards,
- supply-chain security, and
- economic resilience.
These priorities have direct implications for NATO–EU cooperation on emerging technologies, infrastructure protection, and economic security.
Resilience and Hybrid Threats: Hybrid threats—cyber operations, disinformation, infrastructure vulnerabilities—feature prominently. Although the NSS does not propose new institutional mechanisms, it strengthens the rationale for deeper NATO–EU cooperation in:
- cyber defence,
- critical-infrastructure security,
- counter-disinformation,
- information integrity, and
- civil–military coordination.
Given the civilian leadership required for hybrid resilience, the EU’s role becomes even more central within the transatlantic framework.
Strategic Context for Europe: The NSS signals a more selective U.S. global posture, but not disengagement. Alliances remain essential—but expectations are clearer and more demanding.
European Allies must:
- accelerate capability development,
- strengthen industrial and technological resilience,
- enhance readiness, logistics, and mobility,
- protect critical infrastructure, and
- ensure alignment with NATO standards and requirements.
The message is not that the U.S. is stepping back—but that the era of Europe relying on post-Cold War assumptions is over.
Key Takeaways
- End of an era: The NSS declares the post–Cold War model of expansive American global leadership over.
- Atlas no more: The U.S. will not shoulder European security alone; Allies must deliver capability and resilience.
- China as organising principle: Strategic competition drives Washington’s priorities in technology, industry, and infrastructure.
- Europe must deliver: Expectations for readiness, mobility, and industrial output are higher and more explicit.
- Industrial resilience = deterrence: Defence production becomes a central strategic requirement.
- Hybrid threats require NATO–EU cooperation: Cyber, infrastructure protection, and counter-disinformation demand integrated action.
- A recalibrated partnership: The U.S. remains committed, but expects Europe to match responsibility with capability.
IV. Southern Neighbourhood Partnerships
Strategic Signals from the U.S. Ambassador to NATO on the Southern Neighbourhood
At the Milken Middle East & Africa Summit, held on 4–5 December 2025 in Abu Dhabi, the UAE, Ambassador Matthew G. Whitaker, U.S. Ambassador to NATO, delivered a set of strategic messages that elevate the Southern Neighbourhood within the broader Euro-Atlantic security agenda. Although delivered outside Brussels, his remarks align closely with ongoing NATO priorities and the direction outlined in President Trump’s National Security Strategy (NSS).
Ambassador Whitaker’s intervention centred on four strategic themes:
First: The South is structurally essential to Allied security. He highlighted long-term drivers of instability—demographic pressures, Sahel insecurity, fragile governance in North Africa, and persistent terrorist networks. These factors, he stressed, will shape NATO’s strategic environment for decades and cannot be treated as episodic crises.
Second: NATO’s partnerships are strategic assets, not symbolic frameworks. Whitaker underscored the value of the Istanbul Cooperation Initiative (ICI)—the UAE, Qatar, Bahrain, Kuwait—and the Mediterranean Dialogue (MD)—Algeria, Egypt, Israel, Jordan, Mauritania, Morocco, Tunisia. These frameworks enhance cooperation on counterterrorism, maritime security, cyber, and critical infrastructure resilience, giving NATO early warning and operational reach.
Third: Europe must assume greater responsibility for stabilising its southern flank. Echoing the NSS’s post–Cold War recalibration—the United States will not carry global security burdens alone—he emphasised that Europe must invest more substantively in resilience, capacity-building, and long-term engagement across the South.
Fourth: Deterrence now includes whole-of-society readiness. Drawing on Nordic models, Whitaker highlighted civil preparedness, reserve structures, cyber resilience, and protection of critical infrastructure. This reflects a shift in strategic thinking: credible deterrence is no longer only military — it is industrial, technological, and societal.
This point was reinforced through his message on X:
“At the Milken Institute summit ‘Progress with Purpose: Advancing Meaningful Partnerships,’ I stressed that private-sector innovation and industrial capacity are vital to meeting NATO’s 5% defence investment goal and sustaining credible deterrence. We are strongest when government, industry, and civil society act together to build readiness.”
Ambassador Matthew G. Whitaker
Overall Signal: Ambassador Whitaker’s remarks convey a clear expectation: the Southern Neighbourhood is a strategic theatre and European Allies must take a far more active role. NATO–EU cooperation will be essential to address the combined pressures of terrorism, instability, hybrid threats, energy vulnerabilities and migration dynamics.
Key Takeaways
- Strategic theatre, not a side file: The Southern Neighbourhood is a long-term strategic theatre for NATO, combining terrorism, instability, hybrid activity, migration pressures, and energy vulnerabilities. It cannot be treated as a reactive crisis portfolio.
- Partnerships as operational multipliers: The Istanbul Cooperation Initiative (ICI) and Mediterranean Dialogue (MD) are not symbolic frameworks; they are core platforms for counterterrorism, maritime security, cyber defence, and hybrid-threat resilience across the South.
- Europe’s responsibility across the South: In line with the U.S. National Security Strategy, the message is clear: the United States will not carry the southern flank alone. European Allies are expected to assume greater responsibility for stabilisation, capacity-building, and long-term engagement.
- Deterrence as a whole-of-society effort: Civil preparedness, industrial capacity, digital resilience, and critical-infrastructure protection are now part of deterrence. Defence ministries, industry, and societies must move in sync if NATO is to meet the 5% investment ambition with credible outputs.
- The South as an industrial and energy enabler: The Southern Neighbourhood is both a source of risk and a strategic enabler: it hosts key actors in energy, logistics, critical raw materials, and emerging technologies that underpin NATO’s industrial base and operational readiness.
- NATO–EU cooperation as the coordinating backbone: Managing terrorism, hybrid threats, energy risks, and structural migration pressures from the South will increasingly depend on tight NATO–EU cooperation — linking military planning, resilience policies, border management, and external action.
