A lot of it depends on how the US military reacts when civil war II starts. I used to think a majority of it would stand down and let the feds, states and cities go through it. However with Mattis and the rest being insubordinate and hinting at a coup should be tried I suspect they will side with the deep state and the kind of mess in Yugoslavia will be the type of war. But the military grunts on the ground will be taking into account that the people they are shooting are their neighbors and those they don’t kill will be out for revenge against the military members families. This will be a bloody, nasty mess if the left goes there. I pray it doesn’t happen but I don’t think the left is going to agree and will as they did in 1861, force the war upon the country.
The current standing Army of < 1,000,000 is not large enough to hold one medium sized state let alone an entire country as big ad the USA and it's 330 million population. The Army will not even be worth a footnote in history.
It's imperative that a patriot like Trump is CiC when and if a war erupts. If not, a rat CiC will attempt to use the military to crush our side. In that scenario our side can still win, but the cost will be MUCH higher.
Extrapolating from that premise, if a war is to occur, it's better that the left starts it while Trump is president.
