Aside from military, this tactic became obvious to me when space became (again) a theater of conquest around 2010, involving both private and public sectors, internationally. The narrative around space became very strong, sending messages of conquest, entrepreneurship, science, dreams, you name it. At the exact same period, bloomed movies like: Mission to Mars, Gravity, Interstellar. I won't be surprised to see a sur…
On the other have, every American action movie seems to feature guns and explosions and quite a lot of glorification of the military. The military exist to kill people, and to deliver the utmost brutality to others whilst remaining organised, logical and efficient themselves. Guns exist to kill things. Explosive munitions are fundamentally excellent at killing people from a surprisingly long way away, larger than what Hollywood shows. When was the last time you saw a film highlight the loss a family of a minor villain felt when the hero shot him? The true aftermath of an air strike in a foreign country -- lifelong resentment and hatred about the country that provided it? (Vietnam is an interesting place to visit, but don't mention B-52s to the locals). It is an unfortunate but unavoidable fact of humanity that armies are required to exist. There is definitely good that comes from them, ranging from humanitarian aid to the research into high end technology, and I'm not calling for their abolition -- I am not naïve. That is fundamentally why the glorification of the military at all costs is problematic. The ethical arguments for their existence require exploring.
American films, on the other hand, will quite happily show a commando killing hundreds or thousands of people in a teenager-friendly film, yet American culture decrees that showing a single naked person mandates that the film is restricted. That mindset -- boobs bad, guns good, explosions fun and exciting -- is slowly but surely exported across the globe.
I'm going to look forward to the sci-fi space films where the drama is survival in a hostile environment, and infinitely prefer them to war films.
