The rhetoric of both Pence and Trump, referring respectively to "the boundless expanse of space" and the necessity for "American dominance," is inherently science-fictional, but of a particularly American kind. It is not the cooperatist vision of Soviet science fiction, nor the ramshackled approach of British sci-fi (take Doctor Who), and certainly not the Afrofuturist marriage of esoteric technology and indigenous folklore, seen most recently in Ava DuVernay's A Wrinkle in Time.

Instead, it is the projection of the values of Manifest Destiny (that the settler population has an inalienable right to the uncharted lands) into outer space. Not for nothing did Trump's 2020 reelection campaign manager, Brad Parscale, write that Space Force would be "a groundbreaking endeavor for America and the final frontier."
