That's how I read what you said: that Milley, etc, were trying to execute a coup by removing Trump's nuclear powers.
And that's not how I interpret the situation, based on my understanding of the roles and responsibilities of defense officials in the US military and government.
So I asked you to clarify.
No precedents were set here, what the general did is just leadership. he explained what the rules were explicitly to his followers, to ensure that trump didn't collar one of his followers and somehow ram a nuclear strike through without proper approval.
See "Operation of the Nuclear Football": https://en.wikipedia.org/wiki/Nuclear_football#Operation involves informing the SoD and JCS.
naturally, it's far more complicated than that, https://www.armscontrol.org/act/2021-06/features/nuclear-lau... and no precedents were set in this situation.
Time will tell.
