Time would be better spent overthrowing the capitalists at this point than doing that.

That’s a big IF for the military being willing. They are a huge chunk of the budget and that would be a PR nightmare and jeopardize their generally positive public perception

When the military starts killing its own citizens it also galvanizes the population. It’s going to cause massive unrest even if they “win.”

America was formed by a revolution

The military won’t last long if they kill their entire workforce. At best they can have a stalemate, where “they” win, but no longer have anyone to build their weapons and ammo anymore.

The apathy is also almost certainly seeded by bad faith actors.
