The same thing applies to the use of military power. Back in the Cold War era, it was called "Mutually Assured Destruction."
I think that's what Miller was talking about. The threat of military takeover is a card that can be played in this game. Again, it's more game theory.
Miller said he engaged in “the most - one of hte most complex military operations in the history of this country.”
IOW something very out of the ordinary. A threat of military takeover is not a complex military operation.
