You seem determined to establish the idea that powerful govt bureaucrats can overthrow our Constitutional form of govt in a coup - if they are clever - without any recourse under law. I am just as determined to establish the concept that if you are correct then the Republic is finished.
These sort of people will continue to try - have continued to try - until they succeed, and then you seem to imply that the people must rise up in revolt. That sounds like a formula for disaster; and even if the people should be successful, the bureaucrats need only bide their time and try once again.
Boy! Were our founding fathers ever stupid. They couldn't even establish a legal reason for the Republic to survive a coup attempt, so it would seem.
That path was set in the 1910's, and I agree. The government is so far out of constitutional bounds that as far as I am concerned, it long ago breached the deal.
The tension between the ruled and the rulers is part of the human condition. It has always gone on, and will persist until humanity is finally judged by the almighty.
Franklin, I don't know if he's technically one of the founding fathers but i think he is, said "if you can keep it." They knew more about the way things work than our dumbed-down populace does.
Jefferson said that liberty depends on periodic revolt.
