"Dotard has taken the country hostage, and the United States does not bargain with hostage takers."
In theory yeah, but he did it through the political system, not by violent force. Not in the literal sense. I wouldn't go that far to call him a hostage taker though. He was enabled through the working mechanisms of government, as vulnerable as they are/were.
Therefore, you still have to see it through the political lens, and prevent the same levers from being ever again pulled institutionally. Putting presidents in jail is something generally reserved for countries with shaky levels of democracy. I'd rather not sink that low just yet.
Let him go, to never come back, and spend the energy and effort reforming the checks and balances. That is best for America.
I understand the sentiment for a pound of flesh, but I am ultimately a game-theory pragmatist, and that is the best path forward for many boring reasons I will get into if you want more reinforcement to this argument.
