Case Study: The Transatlantic Crisis of 2025-2026
Background Context
The return of Donald Trump to the US presidency has fundamentally altered the transatlantic relationship. What was once characterized as a strategic partnership between democratic allies has devolved into a coercive relationship where Europe finds itself simultaneously dependent on and threatened by its traditional security guarantor.
Key Incidents Defining the Crisis
December 2025 Security Strategy The US released a national security document that targeted the European Union more aggressively than traditional adversaries like China or Russia, signaling a fundamental reorientation of American foreign policy priorities.
Greenland Territorial Threat Trump’s public declaration that he would seize Greenland from Denmark “by force if necessary” represented an unprecedented threat to NATO solidarity and EU territorial integrity. The threat came precisely as European leaders were negotiating post-war security guarantees for Ukraine with US envoys.
Trade Asymmetry The 2025 trade standoff resulted in what European observers characterized as a “lopsided deal” favoring American interests, establishing a pattern of economic coercion.
Political Interference Campaign The Trump administration has openly stated its preference for far-right governments in Europe, with active support expected for Viktor Orbán in Hungary’s April elections and anticipated involvement in France’s 2027 presidential race.
Regulatory Warfare Sanctions imposed on European digital regulations, labeled as “censorship” by the Trump administration, alongside Elon Musk’s sustained attacks on EU institutions through X (formerly Twitter), represent an assault on European regulatory sovereignty.
Europe’s Response Pattern
European leaders have adopted what the article describes as a “playbook” centered on:
- Avoidance of escalation – Refusing to publicly call out Trump’s threats
- Personal diplomacy – Relying on leaders with direct lines to Trump (Macron, Meloni, Rutte)
- Tactical accommodations – Making concessions to prevent worse outcomes
- Strategic patience – Waiting out provocations in hopes they pass
This approach has yielded limited successes, such as maintaining European participation in Ukraine peace negotiations, but has failed to halt the escalating pattern of American aggression.
Outlook: Scenarios for the Next Three Years
Scenario 1: Managed Deterioration (Most Likely – 45% probability)
Europe continues its current accommodation strategy with periodic tactical pushbacks. The relationship degrades steadily but avoids catastrophic rupture.
Key Characteristics:
- Trade tensions persist with Europe making incremental concessions
- US continues supporting European far-right movements without direct intervention
- NATO formally persists but loses operational coherence
- Ukraine receives minimal security guarantees, insufficient to deter future Russian aggression
- European defense spending increases but remains inadequate for true autonomy
Timeline Markers:
- April 2026: Orbán victory in Hungary with visible US support sets precedent
- Late 2026: Additional EU-US trade friction over technology regulations
- 2027: French election becomes flashpoint for US interference debate
- 2028: Potential Trump successor continues similar policies in modified form
Scenario 2: Strategic Rupture (25% probability)
A specific provocation crosses an undefined European red line, triggering deployment of economic countermeasures and fundamental alliance reconfiguration.
Potential Triggers:
- Actual military moves toward Greenland
- Overt US support causing far-right electoral victory in France or Germany
- US withdrawal from NATO or Article 5 guarantees
- Sanctions on major European companies
- Support for separatist movements within EU member states
Consequences:
- Suspension or termination of US-EU trade agreement
- Deployment of anti-coercion instruments against US imports
- Accelerated European military integration independent of NATO
- Realignment of some European states toward alternative security arrangements
- Global economic disruption from transatlantic trade war
Scenario 3: European Capitulation (20% probability)
Unable to achieve defense autonomy and desperate for US security guarantees, Europe accepts a fundamentally subordinate relationship to Washington.
Manifestations:
- Abandonment of regulatory enforcement against US tech giants
- Acceptance of US-preferred governments regardless of democratic concerns
- Trade policy dictated by US interests
- Ukraine settlement on Russian-favorable terms accepted under US pressure
- EU cohesion fractures between Atlantic-oriented and sovereignty-focused states
Scenario 4: Successful European Autonomy (10% probability)
Europe accelerates integration, achieves credible defense independence, and establishes deterrent economic leverage that rebalances the relationship.
Requirements:
- Rapid expansion of European defense production
- Franco-German agreement on nuclear umbrella extension
- Unified EU fiscal policy enabling massive defense investment
- Successful enforcement actions that change Big Tech behavior
- Maintenance of unity despite US interference attempts
Solutions: Strategic Options for Europe
Immediate Actions (0-6 months)
1. Establish Clear Red Lines Europe must privately communicate to the Trump administration specific actions that will trigger economic retaliation. Ambiguity invites testing.
- Implementation: Confidential diplomatic channels backed by public unity statements
- Red lines should include: Physical military action against EU/NATO territory, sanctions on European governments (not just companies), direct funding of anti-democratic movements
2. Accelerate Defense Industrial Coordination Create European Defense Industrial Program (EDIP) to pool procurement and eliminate redundancies.
- Target: Achieve 30% increase in artillery production within 12 months
- Focus areas: Air defense systems, precision munitions, drone capabilities
- Funding: €50 billion emergency appropriation from EU budget
3. Implement Calibrated Tech Enforcement Rather than backing down, escalate enforcement in targeted ways that create business pressure on Musk and other Trump allies.
- Action: Increase X fines to €500 million quarterly for Digital Services Act violations
- Mechanism: Use existing EU competition law more aggressively
- Message: European markets remain attractive but compliance is non-negotiable
4. Create Ukraine Security Framework Establish European-led security guarantee for Ukraine that doesn’t require US participation.
- Components: Troop deployments, air defense coverage, weapons supply commitments
- Purpose: Demonstrate European capability for independent action
- Timeline: Operational framework by mid-2026
Medium-term Reforms (6-24 months)
5. European Defense Union Move beyond coordination toward genuine integration with joint command structures.
- Legal framework: Treaty modification or enhanced cooperation mechanism
- Force structure: 100,000-strong rapid reaction force with joint equipment
- Nuclear dimension: Franco-German dialogue on extended deterrence
6. Strategic Economic Leverage Development Prepare but don’t yet deploy trade countermeasures to create credible deterrence.
- Identify pressure points: US sectors dependent on European markets (aerospace, pharmaceuticals, agriculture)
- Legal preparation: Pre-authorize anti-coercion instrument with specific trigger criteria
- Communicate capability: Ensure Trump administration understands economic exposure
7. Counter-Interference Architecture Develop comprehensive framework to resist foreign electoral manipulation.
- Regulatory tools: Strengthen Digital Services Act with specific provisions on political advertising
- Transparency requirements: Mandate disclosure of foreign funding for political activities
- Rapid response: Create EU task force to identify and counter disinformation in real-time
- Legal framework: Ensure tools designed for Russian interference apply equally to US interference
8. Alternative Security Partnerships Deepen cooperation with democracies sharing similar values and concerns.
- Partners: UK (post-Brexit security cooperation), Canada, Japan, Australia, South Korea
- Format: Democracy Defense Dialogue focused on countering authoritarian and anti-democratic pressures
- Benefit: Reduces isolation, creates alternative to US-dominated frameworks
Long-term Transformation (2-4 years)
9. Genuine Strategic Autonomy Achieve capability to defend European territory and interests without US support.
- Investment requirement: €1.5-2 trillion over decade
- Capability targets: Independent satellite/intelligence systems, strategic airlift, power projection
- Industrial base: Self-sufficient defense production across all critical systems
10. Reformed Transatlantic Relationship If conditions permit, establish new framework based on equality rather than dependence.
- Principle: Partnership of choice, not necessity
- Structure: Issue-based coalitions rather than standing hierarchical alliance
- Foundation: European strength enables genuine negotiation
Impact Assessment
Economic Impacts
Short-term (2026-2027):
- Trade disruption: If economic countermeasures deployed, €200-300 billion in bilateral trade at risk
- Investment uncertainty: Foreign direct investment flows between US and Europe decline 15-25%
- Defense spending shock: Additional 0.5-1% of GDP redirected to military, constraining other priorities
- Market volatility: Transatlantic tensions create sustained uncertainty in equity and currency markets
Medium-term (2027-2029):
- Industrial reorganization: European defense industry expands significantly, creating 500,000+ jobs but requiring massive capital reallocation
- Technology decoupling: Reduced reliance on US tech platforms accelerates European digital sovereignty efforts
- Trade reorientation: Europe deepens economic ties with Asia, Latin America to offset US relationship
- Cost of autonomy: Estimated €300-400 billion in lost economic efficiency from duplicating US capabilities
Security Impacts
NATO Transformation: The alliance faces three possible futures:
- Formal continuation, practical irrelevance: NATO exists on paper but European pillar operates independently
- Reconfiguration: European-led NATO with US as partner rather than leader
- Dissolution: Replaced by European Defense Union with case-by-case US cooperation
Ukraine Conflict:
- Worst case: Europe unable to sustain support alone, Russia achieves favorable settlement, emboldening further aggression
- Middle case: Frozen conflict with inadequate security guarantees, periodic escalation risk
- Best case: European security framework deters Russian aggression, demonstrates credible independent capability
Russian Calculations: Putin likely sees opportunity in transatlantic discord. European weakness could invite:
- Increased hybrid warfare (cyberattacks, disinformation, sabotage)
- Testing of NATO resolve in Baltic states
- Pressure on Moldova, Georgia, other vulnerable states
- Energy coercion resumption if European unity fractures
Political Impacts
EU Cohesion:
- Stress test: Different threat perceptions (Eastern Europe focuses on Russia, Southern Europe on migration/economics) could fracture unity
- Sovereignty debate: Tension between those prioritizing US relationship and those demanding European autonomy
- Institutional evolution: Crisis could accelerate integration or trigger fragmentation depending on leadership quality
Democratic Resilience:
- Electoral interference: If US successfully influences major European elections, establishes precedent undermining democratic legitimacy
- Populist momentum: Economic costs of autonomy could fuel anti-EU sentiment
- Institutional trust: Failure to protect sovereignty could erode confidence in European institutions
Global Order:
- Multilateral system: Further erosion of rules-based international order
- Democracy vs. authoritarianism: Weakened transatlantic unity benefits China, Russia
- Middle power strategy: Other nations recalculate alliances based on US unreliability
- Precedent setting: Trump’s approach could inspire other powers to use coercion against smaller neighbors
Social Impacts
Public Opinion Shifts: Current polls show European public opinion on US has deteriorated significantly, but concrete policy implications remain unclear.
- Security anxiety: Populations in Eastern Europe particularly concerned about US reliability
- Anti-American sentiment: Risk of overcorrection toward reflexive opposition to US
- Political polarization: Different views on US relationship correlate with left-right divide
- Generational divide: Younger Europeans less attached to transatlantic tradition
Identity Evolution:
- European consciousness: Shared external threat could strengthen European identity
- Atlantic vs. Continental: Renewed debate about Europe’s cultural and strategic orientation
- Values definition: Forced clarification of what European values mean in practice when challenged by US
Conclusion: The Necessity of Choice
Europe’s current strategy of accommodation and avoidance is unsustainable. The continent faces a fundamental choice between three paths:
Path 1: Subordination – Accept diminished sovereignty and US hegemony in exchange for continued security umbrella. This preserves formal alliance at cost of European autonomy and dignity.
Path 2: Confrontation – Deploy economic countermeasures and accelerate separation. This risks catastrophic rupture before Europe achieves true independence.
Path 3: Strategic Transition – Managed evolution toward autonomy while maintaining selective cooperation. This requires unprecedented European unity, massive investment, and sustained political will.
The window for Path 3 is narrowing. With three-quarters of Trump’s presidency remaining and critical elections approaching, Europe must move from reactive crisis management to proactive strategy. The decisions made in the next 6-12 months will determine whether Europe emerges from this crisis as a genuine geopolitical actor or accepts permanent subordination to an increasingly unreliable ally.
The stakes extend beyond Europe itself. Success in achieving strategic autonomy while maintaining democratic values would demonstrate that medium powers can defend sovereignty in a multipolar world. Failure would signal that only great powers matter, accelerating the collapse of the rules-based international order.
As Denmark’s Mette Frederiksen warned, the most challenging part is yet to come. Europe’s response will define not just transatlantic relations, but the nature of international order for decades ahead.
