I didn’t mean “someone” this literally. In both cases, many people were directly involved or allowed things to happen by not intervening.
My point was the more general one that a system of government only remains in place for as long as those who have the power want it to. (Whoever that may be: an elite, the people, the military, the clergy, some combination…) The US seems to be entering a phase where a big part of those in power wants to move from liberal democracy towards authoritarianism. If they turn out to have a stable majority and follow through with their plans, then the US Constitution won’t be worth more than the paper it was written on.
They should start calling it the Department of Government Efficiency Department.
