Summary

The German newspaper Welt conducted a war game simulation titled 'Ernstfall' ('Emergency') in December 2025 depicting a Russian attack on Lithuania through the Suwałki Corridor in October 2026. The scenario involved Russia using a humanitarian crisis pretext in Kaliningrad to establish a land corridor linking Belarus and Kaliningrad by force, capturing the corridor within three days. The simulation highlights Russian hybrid warfare tactics including a fake video, cyberattacks disrupting German financial systems, and attempts to split NATO and the EU politically. Despite limited allied preparedness and hesitation especially by the US regarding NATO Article 5 invocation, Germany decided to strengthen Bundeswehr presence and military readiness. The exercise examines Germany's political decision-making under crisis and exposes challenges in NATO cohesion and deterrence posture in the Baltic region. The simulation stirred diplomatic controversy in the Baltics for portraying Baltic states as passive victims rather than active defenders, yet it raised awareness and encouraged practical defense improvements at the operational level. It reflects ongoing vulnerabilities, emphasizes Russia’s use of hybrid and grey zone tactics aiming for a rapid fait accompli while avoiding full-scale war escalation, and underscores the importance of political will alongside military preparedness. The scenario also references historical RAND war games warning of rapid Russian advances in the Baltics and subsequent NATO reinforcement debates.

Classification

Confidence: High

The simulated scenario details a hostile Russian military and hybrid warfare operation aimed at territorial seizure and political destabilization in the Baltic region. It involves deception, cyberattacks, disinformation, and armed aggression forming a comprehensive hybrid attack strategy.
