I served 28.5 years in the Navy. I have been retired since 2010, so take what I say with a grain of salt. I have no 2026 "inside info".
My experience was that the military was a microcosm of America. You had about a 3rd that were conservative, a 3rd that were progressive and a 3rd that were: "I don't give a fuck, just don't cock it up". I could count on one-hand the number of times my Shipmates and I discussed politics. It just wasn't done.
A coup is hard. So is a Civil War. Who's going to get all the aircraft carriers on their side?
I am not dismissing the damage these fucksticks have done, but that damage is to "good order and discipline". Rest assured that if they try a coup, it would be with a hollowed out shell of a once great defense department. You'd have to control everything, down to the E3 that works the flight deck, or the E4 that makes the donuts. The military would destroy itself, before it allowed an asshat like Kegsbreath to prosecute a coup.
That being said, I think your could justify the next Dem President firing every fucking Soldier, Sailor, Airman and Marine above the E5 level, and every fucking federal law enforcement official hired since 2016 within the first 24 hours of his term.
At this point, it's going to be easier to tear this fucking shitshow down to the studs and start over.
Here's hoping we have the courage to rip this fucking cancer out of our government with the same zeal that implanted it.
