And yet, and yet....
I still have to hear a convincing reason why Trump just cleared out all the top civilian defence hierarchy (as opposed to other departments or sectors) and stuffed it with his loyalists.
I think a coup attempt is extremely unlikely, still less a successful one. Also, going on the previous experience of the “mass militia mobilisations” in the Pacific North West that were supposed to be going to “clear away BLM and Antifa” from Seattle and Portland respectively, the trumpeted far right invasion of Washington on Saturday is likely to be another damp squib.
But just for future reference the key objective in such a situation would be to neutralise those parts of the state apparatus that might act against you (rather than necessarily seek to use them offensively).
If you had control over say, vast swathes of police, National Guard, Homeland Security etc, plus hordes of tooled up irregulars and militia you would not need the armed forces - you would just need them to stand aloof from “domestic politics”.
You would not need to take every state or conurbation either. Just the key ones and those where you were strongest, particularly if that would give you control of vast swathes of territory. The hold outs could be dealt with later, or even partitioned off, if that became possible.
To be clear, a modern coup does not need majority support, just the active support of a large enough armed minority and the passivity of the majority naively hoping for “peaceful and legal solutions”. It does not need the active support of the armed forces (just their “neutrality“). It does not need international support - particularly when you are a superpower - just other major powers “standing aloof”, or covertly feeding the flames.
As I say, I think Trump is finished and will likely go with a whimper rather than a bang, but we cannot afford to be complacent that “coups can’t happen in the advanced West” - this is exceptionalism.
