 Heinlein's books, and "Starship Troopers" in particular, had an enormous impact on political science fiction, to the extent that author Ken MacLeod has stated that "the political strand in [science fiction] can be described as a dialogue with Heinlein," although many participants in this dialogue disagree with Heinlein.Science fiction critic Darko Suvin states that "Starship Troopers" is the "ancestral text of U.S. science fiction militarism" and that it shaped the debate about the role of the military in society for many years.As well as his political views, Heinlein's ideas about a futuristic military as depicted in the novel were deeply influential among films, books, and television shows in later years.
