Germany has lost the jihadi war without even fighting. This is too little, too late.
Adorno’s later works, such as The Authoritarian Personality, explored the idea that modern societies could generate passive, conformist individuals through mass culture. This had a lasting influence on post-war German intellectual thought. They saw that conformism as a major problem but then created the same kind of conformism with their Critical Theory indoctrination.
Horkheimer and Adorno’s intellectual framework also influenced the restructuring of the German educational system, encouraging critical theory (get that, not "critical thinking," "critical theory" aka "Marxist liberation theology").
In summary, while not political actors, Horkheimer and Adorno were highly influential in shaping the intellectual and philosophical climate of post-war Germany. Their critiques of rationality contributed to the cultural and academic rebuilding that supported the development of the rot we see today in Germany.
