I (Tim) wrote an article for The Bulletin of the Atomic Scientists (the keepers of the Doomsday Clock!) about the appropriation of nuclear weapon imagery and themes in Rogue One and Star Wars. I am talking about the Death Star, of course.
Here is a highlight:
The central plot of Rogue One involves our heroes stealing the blueprints to a new secret weapon of the evil Galactic Empire: the Death Star, a moon-sized, space-based battle station equipped with a laser capable of destroying an entire planet in a single stroke. There is hope that the plans could hold the key to finding a weakness in the station that could be exploited by the Rebellion to start a “chain reaction” and put an end to the weapon.
The Death Star, in Star Wars generally and particularly in Rogue One, serves as a stand-in for the nuclear weapons arsenal with all the accompanying nuclear imagery, deterrence theory, and dangers shown to the audience. Rogue One deploys the Death Star as a visual, technical, and thematic stand-in for thermonuclear weapons.
