For your consideration ...
Pretty sure there is, for decades been, a highly classified patriotic special operations unit/team/group that is, has been, created and tasked, with putting down such skulduggery should any President have a need to, and so chooses to, squash any rogue insubordination at such high levels to ensure any such individuals are removed post haste, should such actions come into play. Not by killing, unless absolutely necessary given no choice, but with the highest level show of force as to send an extremely loud public message. (Should the regular removal process not be sufficient.) Also, pretty sure such suborning anti-American behavior/actions against a sitting President in high military ranks would fall under acts of treason and be prosecuted as such, after removal.
Short of all this, I'm placing my money on Trump court-martialing, firing, or forcing the retirement of many a high level military personnel. I also see a complete turn over of the entire Joints Chiefs of Staff with non-woke true patriotic American Generals and Admirals, as well as loudly firing the Secretary of Defense, Lloyd J. Austin.
