Rereading the portions of the QMap where "The Hunt for Red October" signature is used makes me think the "defector/secret weapon" angle is more likely here - specifically someone has given the Trump admin blackmail info on mainstream media/Hollywood personalities that was previously used to control them and shape the media narrative.
Q ruled out the Argentinian sub angle.
The Hunt for Red October is about the release of all the blackmail material on MSM/Hollywood personalities who were previously blackmailed to control the media narrative, causing them to resign or be fired.
It makes strategic sense for this to occur prior to the public arrest/roundup of the US Cabal - Clinton/Podesta/Obama/McCain etc. The absence of these media personalities will weaken (((their))) ability to spin it as a fascist takeover by Trump and provoke a civil war.
