Marathe & Steeply: the threat is homegrown — someone killed your nation
This is a U.S.A. production, this Entertainment cartridge. Made by an American man in the U.S.A. The appetite for the appeal of it: this also is U.S.A. The U.S.A. drive for spectation, which your culture teaches.
Context
The pickup's core, and the theme's deepest cut: the weapon is not Québécois but American ("a U.S.A. production... The appetite... this also is U.S.A."), so the real threat was internal long before the samizdat — "someone sometime killed your U.S.A. nation already." The diagnosis is political, not moral: a failure of "authority" that "let you forget how to choose," a nation hollowed from within by its own abdication. Québec did not kill America; America's own history did, and the Entertainment only reveals the corpse. (The spectation/appetite and choosing-your-master philosophy are entertainment-self's; landed here is the national-diagnosis substance the plan routes to us.)
