Actually, I could come up with a pretty good list of reasons to be suspect that it (reversal) could be a possibility, (major foreign involvement, mass infiltration, treason, protection of the Constitution, prior meeting with 8 Generals, sudden administration changes, etc.) but a minute possibility and I figure the "smooth transition as promised" is more likely in regards to the guise of the control needed to keep those on the Right under control, -which once again makes this appear to be a serious overkill that causes one to question the true reasons for it. <-since it is Trump who is full control of these troop's deployment and DC is a hotbed for ANTIFA and BLM radicals where it might be necessary to control them but not so much for the Right and seems a kind of ridiculous sideshow if suggesting this is actually necessary to control the Right.
The most likely reason for this overkill is to try to set the stage for why weapons need to be confiscated... - which is yet another Constitutional attack being this is the true reason for the 2nd Amendment which is to keep the government in check.
Since there are 30,000 and they think there may be trouble... This former Vietnam Combat Marine says, don't shoot um, put them in a uniform and recruit them... Then send them out of the good US of A to a foreign country to a kill zone and see if they can survive!... Brother Glen... OORAH!
