My guess, "The Alliance" would be a QAnon trope, a confederation of select "White Hats" in the US military and parts of US government (and other select humans) and some alien "Arcturian" UFO contingent. They are trying to overthrow the Deep State (corrupt civil/intelligence/military service in USA and Western governments) that are colluding with "globalists" and exploitative capitalists to economically and socially oppress "good white people of European descent" and corrupt their morals and dilute their influence and moral strength. Presumably The Alliance chose Trump to become President in 2016 as part of an attempt to awaken the masses and usher in "The Great Reset / The Storm / The Awakening" where global corruption will be exposed, corrupt politicians, businesspeople, officials, cultural influencers will quickly be judged and executed.
There are many variations on this theme, and though not widely held as a belief, elements seep into the wider discourse and thought.
I'm not sure what the aliens' motivation would be in this scheme, and often they're not part of the story.
EDIT: here's a random page that likely will bring more questions than answers but it references the elements described above ... https://divinecosmos.com/davids-blog/22143-moment-of-truth-q... ... there are variations of this conspiracy theory tailored to many different tendencies: New Agers, Evangelical Christians, White Supremacists, Conservative Republicans, etc. For a further look, find interesting interviews with a certain Jan Halper Hayes and her supposed work with USA Space Force. Some of these promoters a true believers, others are grifters. Also ... grand corporatists and communists are usually conflated in these narratives.
It's sort of a wonder that this screenplay has not yet been a major hollywood production. I mean, sure, anything QAnon is terribly uncool for us informed types /s but its hard to believe that this would not be a major success if done with high production values and non-cheesy script.
Something vaguely related to next year's A24 release "Civil War", but much more QAnon-adjacent and informed. Even better if Q would denounce it all as an attempt to "innoculate people from the truth".
