I was in Berlin back then. No comparison - back then our enemies were overseas for the most part, not 1/2 of our voting electorate.
Enemies foreign and domestic meant foreign then. Not now.
If the boogaloo starts now, we can fix it. Better to be offense than defense sometimes - this time is soon. (Yeah, I was Infantry in Berlin back then, clearing Anarchists that were squatting in apartment buildings, the Polizei looked the other way when we used real combat in cities techniques.
Fun times....
We used frags on Antifa in the good old days....
I was at Graf for Gunnery. Ended up being stuck there a few extra days because they stopped all military convoys.
We may have the same opportunity here and the enemy has been (conveniently) self-identifying.
