I'm going to give my view on SCOTUS taking the Lin Wood GA case, Powell's MI case, and POTUS's PA case, and I'll be assuming there'll be no military action whatsoever as they take it up for the conference on 2/19.
SCOTUS dismissed the TX case, according to their own words, because it was filed under the wrong Article of the Constitution. POTUS's case was exactly the same lawsuit, but filed under the correct Article. For a reminder, this case only involves PA switching around the election laws at the last second, and alleging that it was unconstitutional (it is). Lin Wood's lawsuit does the same thing for Georgia, while Sidney Powell's lawsuit is the only one there that actually shows proof and evidence of the voting machine switching the votes.
What I expect will happen is that SCOTUS will decide to not give a shit, the election's over, and they'll say "it's not our problem anymore" and they'll dismiss all three cases. And even in the case that they do take the cases or one of them, it's likely that they won't even hear them until October.
Now, just for a thought experiment, I'm going to assume the opposite and believe there's still some secret uber Plan to save the Republic. If I was the military and I wanted to uphold the rule of law to the best of my ability (even though my enemies flaunt it at every single opportunity), but I also knew that Biden would become false POTUS by any means necessary, I'd make damn sure that we retake the SCOTUS and give them the power to order a new election, after negating the effects of voter fraud, so as to protect every future legitimate President. This also prevents the need for Plan Z, although it would allow for a whole shit ton of "Precipice" for the normies.
