Eastern Flank Security: EU Pushes Urgent Russia Plan
The future of Eastern Flank security is coming under renewed scrutiny after five European Union commissioners from countries on the bloc’s eastern border urged Commission President Ursula von der Leyen to take faster action against growing Russian threats.
The commissioners want the European Commission to appoint a high-level special coordinator for the region. They say the position could give affected countries a single point of contact and help coordinate European responses to security challenges ranging from drone incursions to attacks on critical infrastructure.
The proposal comes as concerns rise across the Baltic and Nordic regions about the possibility that Russia’s war against Ukraine could create wider security risks for European countries bordering Russia.
Eastern Flank Security Faces Growing Pressure
The EU’s eastern border has become one of the most sensitive security areas in Europe.
Countries including Estonia, Latvia, Lithuania, Poland and Finland are increasingly focused on military preparedness, infrastructure protection and resilience against hybrid attacks.
The European Commission has already identified the eastern border regions as facing a combination of security and economic challenges. Its February 2026 strategy highlighted hybrid warfare, drone incursions, weaponised migration, attacks on infrastructure, disinformation and economic disruption as major concerns.

The latest intervention by the commissioners therefore comes against a broader effort to strengthen Europe’s ability to respond to threats that do not always take the form of conventional military attacks.
For governments in the region, the concern is not limited to a potential large-scale military confrontation. Smaller incidents can also create pressure if they repeatedly test national airspace, disrupt infrastructure or undermine public confidence.
Five Commissioners Call for a Special Coordinator
In late July, EU foreign policy chief Kaja Kallas, Executive Vice-President Henna Virkkunen and Commissioners Valdis Dombrovskis, Andrius Kubilius and Piotr Serafin wrote to von der Leyen with a series of recommendations.
One of the central proposals was the creation of a special coordinator dedicated to the EU’s Eastern Flank.
The role would be designed to improve coordination between the European Commission, national governments, NATO and other relevant authorities.
The commissioners argue that a single senior official could help identify security gaps and ensure that European resources are directed toward the areas most in need.
The proposed coordinator would also work on civil preparedness and critical infrastructure protection.
That could include infrastructure such as energy networks, transport systems, communications facilities and other assets considered essential to the functioning of communities and economies.
Why Eastern Flank Security Matters to the EU
The debate over Eastern Flank security reflects a broader change in the way European governments view their eastern borders.
For many years, border security was largely treated as a national responsibility. Russia’s full-scale invasion of Ukraine has changed that calculation.
The European Commission now describes the eastern border regions as strategically important to the security and stability of the wider EU.
Its 2026 strategy covers nine member states affected by the security environment around Russia, Belarus and Ukraine. The Commission has also outlined measures involving infrastructure, defence capabilities, energy security, digital connectivity and civil preparedness. EEuropean Commission+1
The argument is straightforward: instability on Europe’s external borders can quickly affect the wider European economy and security environment.
A damaged power network, disrupted railway, cyberattack or drone incident may begin as a local event. However, repeated incidents can create significant pressure on governments and businesses.
That is why European policymakers increasingly describe resilience as part of security rather than as a separate policy area.
Baltic States Seek Stronger European Support
The Baltic states are at the centre of many of these concerns.
Estonia, Latvia and Lithuania border Russia or Belarus and are geographically close to areas where military activity has increased since Russia launched its full-scale invasion of Ukraine.
Their governments have repeatedly called for stronger deterrence and better protection against hybrid threats.
The EU commissioners have therefore proposed that the European Commission hold a meeting in one of the Baltic states this autumn.
The purpose would be more than symbolic.
The commissioners say a visit could allow senior EU officials to see the security and economic challenges facing the region directly and better understand the concerns of local governments and communities.
Such a meeting could also demonstrate political support at a time when Eastern European governments want European institutions to remain closely engaged with their security concerns.
Eastern Flank Watch Could Be Accelerated
Another major part of the proposal involves the EU’s Eastern Flank Watch initiative.
The project is intended to strengthen the bloc’s ability to detect and respond to hybrid threats along its eastern borders.
The European Commission has already included Eastern Flank Watch among several initiatives intended to strengthen security and resilience in eastern regions. Other projects include European Drone Defence, the European Air Shield and the European Space Shield. EEuropean Commission
The commissioners are now calling for the initiative to move faster and receive additional funding.
The urgency is linked partly to an increase in reported airspace violations and drone incursions in and around European territory.
Drones are particularly challenging because they can be relatively inexpensive, difficult to identify quickly and used for a range of purposes.
European governments are therefore investing in detection systems, air defence and counter-drone technology.
NATO Is Also Strengthening the Eastern Flank
The EU is not acting alone.
NATO has significantly increased its focus on the alliance’s eastern flank since Russia’s invasion of Ukraine.
According to NATO, Russian drones and aircraft violated the airspace of several NATO countries in September 2025. The alliance responded by launching Eastern Sentry, a reinforced vigilance activity covering the eastern flank from the High North to the Black Sea. NNATO+1
The initiative brings together additional aircraft, air-defence systems, surveillance capabilities and other assets.
NATO says the goal is to improve vigilance and strengthen deterrence.
The alliance has also expanded its work on hybrid threats. NATO defines hybrid threats as activities that can combine military and non-military, overt and covert methods, including cyberattacks, disinformation, economic pressure and attacks on critical infrastructure. NNATO
This distinction is increasingly important for Europe.
A security threat does not necessarily begin with tanks crossing a border. It can involve cyber operations, sabotage, information manipulation or attacks on infrastructure.
Russia Remains a Major Security Concern
NATO currently describes Russia as the most significant and direct threat to the security of its members.
The alliance says Russia has used a range of aggressive hybrid activities, including critical infrastructure sabotage, cyber operations, disinformation, political interference and provocative actions around Allied borders. NNATO
European governments on the eastern flank have consequently pushed for stronger cooperation between national institutions, the EU and NATO.
The proposed EU coordinator could help address one of the central challenges of the security environment: fragmentation.
Different threats are often handled by different institutions.
A cyberattack may involve national cybersecurity agencies. A drone incident could involve police, military and aviation authorities. Damage to infrastructure could involve civilian ministries and local governments.
Meanwhile, NATO may have responsibility for military deterrence while the EU can provide funding, regulatory coordination and economic support.
A dedicated coordinator could potentially help connect these different strands.
Critical Infrastructure Is Becoming a Security Priority
Protecting critical infrastructure is another key part of the Eastern Flank security debate.
Modern European economies depend heavily on interconnected systems.
Electricity grids, telecommunications networks, railways, ports, pipelines and digital infrastructure can all have strategic importance.
The European Commission’s eastern-region strategy specifically highlights infrastructure resilience, transport connections, energy security and digital connectivity. EEuropean Commission
This approach reflects a broader understanding of national security.
A country does not need to suffer a conventional military attack to experience serious disruption.
A prolonged cyberattack on public services, sabotage of transport infrastructure or disruption of energy supplies could create economic and political consequences without a traditional battlefield.
For countries close to Russia and Belarus, these risks are particularly difficult to ignore.
The EU Wants Faster Preparedness
The commissioners’ proposal also focuses on preparedness.
They have called for faster action to improve the EU’s ability to respond to infrastructure disruptions, strengthen regional stockpiles and counter hybrid threats.
Preparedness can include emergency supplies, communications systems, energy resilience and mechanisms that allow governments to cooperate during crises.
The European Commission has already announced a wider strategy to support eastern border regions, including funding and initiatives designed to improve security, economic resilience and regional development. EEuropean Commission+1
That means the latest proposal is not starting from zero.
Instead, the commissioners are asking the Commission to accelerate measures already under development.
A Difficult Balance for Ursula von der Leyen
For von der Leyen, the proposal presents both an opportunity and a challenge.
A new coordinator could provide greater political focus to Eastern Flank security. It could also reassure governments that believe the region needs stronger representation within the EU’s decision-making structure.
However, creating another senior position would only be effective if it has clear responsibilities and sufficient resources.
Coordination is useful only when institutions have the authority and funding needed to act.
The EU must also avoid unnecessary duplication with NATO.
NATO remains the central military alliance for the defence of its members, while the EU has major powers in areas such as financing, infrastructure, sanctions, industrial policy, cybersecurity and resilience.
The two organisations therefore have different but overlapping roles.
NATO itself stresses the importance of cooperation with the European Union when dealing with hybrid threats. NNATO
What Happens Next?
The immediate question is whether von der Leyen will endorse the proposed coordinator.
The commissioners are also seeking stronger funding for Eastern Flank Watch and a political visit by the College of Commissioners to a Baltic state.
If adopted, the proposals could strengthen the EU’s political focus on countries bordering Russia and Belarus.
They could also help create a more coordinated European response to incidents that fall between conventional warfare and peacetime activity.
For the countries on the frontline, however, speed will be critical.
Security risks can develop faster than European institutions traditionally make decisions. Drone technology is advancing, cyber threats evolve rapidly and critical infrastructure is increasingly interconnected.
That creates pressure on policymakers to move from planning to implementation.
Eastern Flank Security Could Shape Europe’s Next Defence Era
The debate over Eastern Flank security is ultimately about more than the Baltic states.
It reflects a fundamental change in Europe’s security environment.
The EU is increasingly treating resilience, infrastructure protection, defence investment and regional development as interconnected parts of security policy.
The commissioners’ call for a special coordinator is therefore significant because it seeks to give the eastern border a stronger voice inside the European Commission.
Whether the position is created or not, the underlying issue is unlikely to disappear.
Russia’s war against Ukraine continues to shape European defence planning, while NATO and the EU are expanding their efforts to counter hybrid threats and strengthen resilience.
For countries on Europe’s eastern edge, stronger coordination is not simply a bureaucratic improvement. It is increasingly viewed as a necessary part of protecting communities, infrastructure and national security.
The next phase of Europe’s response will depend on how quickly political commitments are converted into practical capabilities.
With the eastern flank facing increasingly complex security challenges, European governments are making clear that preparedness can no longer be treated as a long-term option.
