I read something a while back about Trump using Monte Carlo simulations to evaluate a course of action.
They certainly knew since 2015 that CJ Roberts was compromised so it follows that they built into the plan the potential for a roadblock at the Supreme Court. It remains to be seen how many other newcomers to the Court are also compromised.
It seems inconceivable to me that if enough of the Justices cannot be counted on to right the ship legally that the military leaders will simply throw up their hands and say “Oh well. We tried. I guess we’ll be communists now so we don’t have a civil war.”
Of all the people in the land, I would think that the military are the least likely group to tolerate the Chamberlain doctrine of “Peace At All Costs”.
