The future is not something that has already been decided; it is something we must all shape together. Florence Gaub has long emphasized this principle. In her view, the fact that we so often forget this and retreat into a passive fatalism is one of the major problems of our time. In “Szenario”, the political scientist therefore casts readers in the role of active shapers of world politics as they move through the book from one episode to the next on the basis of concrete decisions. Whether they come into contact with Russian security experts, space military actors or lobbyists in Brussels is determined interactively. The diversity of readable futures not only brings the book’s form and argument into creative resonance; it also shows, in ever new ways, just how fascinating international politics can be.
