Whilst that seems like the best 'fantasy football' outcome with the state making an emphatic and terminal show of strength to remind the trumpists who they're fucking with, the reality is that something along those lines is likely to spiral into a proper doomsday scenario in very short order.
Around 74 million people voted for Trump in the 2020 general election and although a lot of those aren't armed crazies, there are a significantly prolematic number of them who are and they are distributed throughout the continental US. Even if only 4% of them are genuine armed nutters, that's still 3 million under arms. Even if all of the army reserves and national guard were brought into the mix, the regular us military would still be outnumbered more than 2:1 by the militants (of which there are tens of thousands of 'disorganised' militia in their number, a lot of which are comprised of ex-military personnel). Yes, these irregulars do not have an airforce or heavy armour but, you know, it's not like the regular US military has an unblemished track record against lightly armed insurgent and guerilla forces...
If you recall in the 2020 election, a significant number of statehouses and counting centres had an overtly peaceable, but nontheless heavily armed, contingent of walts and dickheads amassed outside the doors (and in some cases (Michigan), gained entry). How do you reckon those AR-toting Yahoos and Boogaloo boys are going to react if the National Guard or regular Army started mowing down their fellow insurrectionists in their hundreds? Especially as a lot of these statehouses and counting centres are poorly defended... The trumpist rot is also present within the ranks of the armed forces. How many soldiers do you reckon will turn their weapons on their own side as they see a bunch of people they are ideologically wedded to get wiped out in front of them?
A big, splashy show of force is generally successful against an outnumbered opponent with shaky morale. It tends to backfire against an opponent that presents a credible threat and is actively seeking a civilisation-ending conflagration so they can rebuild the world anew from the ashes in their image. The trumpist movement for years has been charicatured as a fascist one but in recent times it has moved from one that has cosplayed fascism to one actively embracing it and becoming fanaticised in the process. A massacre of their numbers will not break them like it might have done 4 years ago, this time around it might be just what some of them a looking forward to in order to get the ball rolling and start the second civil war proper.
The best you can hope for is that they shrug and go home when confronted by ranks of military personnel protecting the capital. Any step-up in violence from that point could prove disastrous -and not just for the US.
