Hmm. Not sure exactly how many exist as you ascribe.
During my time in the military it was taught that you only obeyed lawful orders, and that at no time would “just following orders” be considered a defense of any sort. We were also taught that if the situation on the ground changes, you devise a new plan that will work and carry that out. Not that there is never a time to hold your ground in the face of insurmountable odds, but work to avoid that.
This change in thinking from how personnel in other armies operate is what Blackjack Pershing brought to the table a the United States and it was inculcated into the boot-camp training system that he devised. And that training is why even the bulk of Marines (assuming they are putting any effort into the proscribed professional reading list) consider Pershing to be the greatest general the United States has ever had.
So basically while generals and the ranks follow orders, they are trained not to do so blindly, and indeed that they have a personal responsibility to question them or disobey them under some circumstances.
I do believe if it comes to war Trump will retain control of the bulk of the military, but during his eight years in office Obama worked hard to persuade as many pajama boys as possible to sign up. There would probably be splintered factions
I understand and appreciate your points. I don’t think we will get to a situation where the senate gets 67 votes to convict assuming there were an impeachment.
My recollection was the military voted heavily for Trump. Without a conviction, I don’t see them going against Trump due to some sort of incapacitated declaration. I hope the anti-Trump forces don’t go there.
