Early appointments hard core, and primarily directed at those departments that you need to prevent a coup by the permanent government against the president, or make a self coup by the president against the permanent government.
Later appointments softcore cuckservative, and directed at those departments that are irrelevant in the event of a coup.
A big exception to this is the Department of State, which applies semi soft power to overthrow foreign governments and manipulate political outcomes within America. It does not directly control anything that can be directly used to make a coup, except for organizations like the CIA for which Trump has already chosen an establishment figure who is nonetheless extremely hostile to the State Department, but it does control the NGOs that can send out a mob of protesters to delegitimize the government and provide justification for a coup. Trump’s plans for dealing with the State Department (coup central) are unclear. I conjecture he is going to promise them someone they are happy with, then change his mind a few weeks after becoming president, once he has his own men in the army, the FBI, and the justice department.
