EU Leader Outlines Concessions Russia Must Make for Peace Amid Escalating Conflict and Strategic Shifts

As the Russia-Ukraine conflict enters its second year, the international community remains steadfast in its stance that any sustainable and just peace must be anchored in clear, enforceable commitments from Russia. High-level declarations from European Union (EU), NATO, and allied leaders continue to emphasize that Russia’s full withdrawal, accountability for war crimes, and robust security guarantees for Ukraine are non-negotiable. Recent military escalations, diplomatic deadlocks, and strategic initiatives underscore both the volatility of the situation and the evolving efforts to shape a durable resolution.

Reinforced Conditions for a Just Peace

EU leaders, led by figures such as Estonian Prime Minister Kaja Kallas, reaffirm that peace cannot come at the expense of Ukrainian sovereignty or justice. Their core demands remain unwavering:

• Complete withdrawal of Russian forces from all Ukrainian territories, explicitly including Crimea and the Donbas.
• An end to all hostilities and military operations.
• Accountability for war crimes committed during the conflict, ensuring justice under international law.
• The establishment of enforceable security guarantees to deter future aggression.

Leaders stress that any peace agreement must be legally binding, supported by international mechanisms capable of enforcing compliance. Superficial ceasefires or strategic pauses are deemed insufficient, as Russia might exploit such gaps to renew hostilities or buy time for strategic repositioning.

Military Escalations and Diplomatic Deadlock Deepen

Despite ongoing diplomatic efforts—including recent US-mediated talks in Geneva on February 17-18—major breakthroughs remain elusive. Both Kyiv and Moscow maintain rigid positions:

• Ukraine accuses Russia of stalling negotiations intentionally, employing military pressure to extract concessions.
• Russia continues military escalation, employing missile strikes, drone attacks, and ground troop movements aimed at degrading Ukrainian defenses and increasing diplomatic leverage.

Recent Military Developments

• Ukrainian forces have accelerated offensives near Pokrovsk and other strategic eastern regions.
• According to the Institute for the Study of War (ISW) assessment on February 25, 2026, Russian offensives continue to focus on advancing in eastern Ukraine, deploying heavy artillery, and attempting to encircle key Ukrainian positions while facing determined resistance.
• Agencies like Reuters report an uptick in artillery exchanges, missile strikes, and drone attacks, especially targeting Ukrainian infrastructure in the east.
• Russia persists with missile and drone assaults on civilian infrastructure, aiming to erode Ukrainian resilience and exert diplomatic pressure.

This escalation highlights the fragility of the current ceasefire and underscores the urgent need for credible deterrence measures. The conflict remains highly volatile, with ongoing military provocations fueling a precarious stalemate.

Western Response: Strengthening Deterrence and Defense

In response to mounting provocations, NATO and the EU are intensifying their strategic signaling, military readiness, and hybrid threat defenses:

• Multinational drills off northern Germany involve 13 countries, demonstrating NATO’s resolve with thousands of troops, ships, and aircraft.
• NATO Secretary General Jens Stoltenberg reaffirmed that long-term stability depends on both diplomacy and deterrence, emphasizing measures such as diversifying energy supplies, enhancing nuclear safeguards, and maintaining high military readiness.
• The "European Defence Chiefs Unite in Kraków" summit and other forums underscore unwavering unity and a commitment to respond decisively to future Russian threats.

Technological and Naval Enhancements

European and NATO officials are investing heavily in counter-hybrid threat capabilities:

• The European Commission has launched an Action Plan on drones and counter-drone systems to detect, intercept, and neutralize hostile unmanned aerial threats.
• NATO has deployed MEROPS layered counter-drone defense systems, designed for effective, low-cost mitigation of drone-based hybrid attacks.
• Naval power is being expanded: the French Carrier Strike Group, led by FS Charles De Gaulle, has been deployed to the North Atlantic and Baltic Sea, projecting power and securing vital maritime routes.

Political Coordination, Challenges, and New Strategic Initiatives

Recent summits, including the E5 defense ministers’ meeting in Poland, highlight coordinated support for Ukraine and counter-hybrid tactics. Efforts focus on enhanced cooperation among European defense agencies and NATO allies, with specific timelines and capability commitments.

However, internal political disagreements threaten unity:

• Disputes over "fair burden sharing" persist, with some member states hesitant or slow to rearm, potentially weakening collective deterrence.
• European rearmament efforts remain uneven, risking undermined alliance effectiveness if divisions deepen.
• Logistical disparities and strategic divergences require ongoing political will and coordination.

Broader U.S. and Allied Strategies

The U.S. continues to play a pivotal role:

• Deployment of advanced systems like MEROPS and long-range missiles aims to counter hybrid and cyber threats.
• Emphasis on cybersecurity, with the EU revising its Cybersecurity Act to establish a European Cyber Shield—enhancing resilience against cyberattacks.
• The U.S. and NATO are also boosting maritime security and regional surveillance, with Ireland seeking closer cooperation to strengthen maritime and subsea surveillance capabilities.

New Frontiers in European Deterrence and Strategy

Macron’s Revised Nuclear Doctrine

On February 26, French President Emmanuel Macron announced a revised nuclear posture, aiming to modernize France’s nuclear forces amid European security concerns. Macron emphasized that France’s nuclear arsenal remains a key pillar of European security and will be adapted to evolving threats, including hybrid warfare and escalation scenarios. This move underscores France’s desire to assert greater strategic independence and reinforce regional deterrence, signaling to Russia and allies alike that Europe’s nuclear deterrent remains vital.

Poland’s Defence Spending Surge

In a significant strategic shift, Poland committed to raising its defence expenditure to 4.8% of GDP by 2026, up from the current 3.9%. Foreign Minister Radosław Sikorski stated that this increase reflects Poland’s determination to bolster its military capacity in response to ongoing threats from Russia. The enhanced funding will support modernizing forces, expanding troop numbers, and acquiring advanced weaponry, positioning Poland as a central pillar of NATO’s eastern flank.

Latest Strategic Assessments: Military and Deterrence Implications

The latest assessment from ISW offers a detailed operational picture:

"Russian offensives continue to focus on eastern Ukraine, employing heavy artillery and missile strikes to break Ukrainian defenses. Ukrainian forces are conducting counteroffensives near Pokrovsk, aiming to regain lost territory and disrupt Russian supply lines. Despite some tactical gains, Russian forces face stiff resistance, and the front lines remain fluid, with both sides suffering significant casualties."

Bloomberg analysis highlights that France’s renewed nuclear posture and NATO’s increased military readiness are strategically designed to deter escalation and reassure allies. The move signifies a shift toward multi-domain deterrence—combining conventional, nuclear, cyber, and hybrid capabilities—aimed at preventing further Russian advances and maintaining regional stability.

Current Status and Broader Implications

The conflict remains highly volatile, with ongoing military escalations, diplomatic impasses, and strategic shifts. Russia shows little sign of accepting the core demands of full withdrawal, accountability, and enforceable security guarantees. The increase in missile, drone, and naval operations underscores the fragility of the ceasefire and the importance of credible, multi-domain deterrence.

The international response—focused on military readiness, hybrid threat mitigation, and diplomatic engagement—aims to prevent further escalation and uphold Ukraine’s sovereignty. The recent moves in nuclear policy and defense spending illustrate a strategic shift toward heightened deterrence and regional resilience.

Conclusion: Navigating Complex Challenges for Peace and Security

The evolving landscape underscores the critical importance of enforceable guarantees, strategic deterrence, and diplomatic agility. While diplomatic negotiations may continue, Russia’s resistance to core demands and ongoing hybrid threats present significant obstacles to peace.

The overarching goal remains: a peace rooted in justice, legality, and lasting security for Ukraine and Europe. Achieving this depends on sustained Western unity, innovative deterrence measures, and diplomatic flexibility. The coming months will be decisive in determining whether a durable, just peace can emerge—one that preserves Ukraine’s sovereignty and ensures regional stability for the long term.
