The rhetoric and reality of tectonic shifts in Europe and transatlantic relations since the Russian attack on Ukraine will be analyzed from various angles. Defense relations have been altered within Europe as well as Nato. Energy security moved front and center, altering and accelerating moves towards alternative and renewable energy sources. Despite these enormous pressures, the German traffic light coalition had difficulties adjusting its budget accordingly, while the French nuclear industry struggled to meet expectations. Beyond breathing new life into Nato (which was declared “brain dead” by President Macron and put into question by President Trump not long ago), Russia tries to influence the political discourse in the West, supporting anti-establishment groups and spreading disinformation. This major land war in Europe has changed the equation for European security cooperation and Nato as much as it has upended German and EU “Ostpolitik.” The US is asking for a stronger European pillar in Nato but is weary of any strategic autonomy. How can this and other transatlantic conundrums be resolved? What could Europe’s contributions be to a stable peace in the East?
