“How can we support Ukraine against the Russian aggression without risking an uncontrollable escalation?” The question of how far Germany and the European Union should support Ukraine in the fight against Russian aggression is the subject of intense debate. Thomas Risse refers to the article "Krieg und Empörung" by the philosopher Jürgen Habermas, published in the Süddeutsche Zeitung, and criticises the playing off of rational argumentation and emotionality. The Habermasian position would put the risk of nuclear war in the foreground, while the threat to the liberal international order is the real risk, writes Risse.
