For many, game theory sounds like dry mathematics, like formulas, like something that only plays a role in lectures or business games. In reality, however, it is an ancient thinking tool that existed long before its academic formalization. Diplomats used it, commanders used it, captains of industry used it - long before it was even called that. In the end, it is nothing more than a sober question:
„When several players have to make decisions in an uncertain situation - what options do they have and what are the consequences?“
This kind of thinking has become surprisingly rare today. Instead of analyzing alternatives, much is narrowed down to moral narratives or spontaneous interpretations. Yet in geopolitical issues in particular, a clear analysis of the possibilities would be the foundation of any mature policy. It is precisely this old craft that I would like to take up again in this article.
