They are going to find out the hard way that it can happen here, if we don’t stop it
To get a degree in German I had to take several courses in German literature. As late as the 1980’s their literature consisted not of “It can’t happen here,” but rather “how did we allow this to happen?” German authors and playwrights came up with a number of pointed works on the subject, my favorite was “Biedermann und die Branstifter.” (Biedermann and the Arsonists). It’s a story of the average bourgeois man who lets three thugs live in his upstairs apartment. They openly tell him they are going to burn down the entire town, and brazenly go about their plans out in the open. Biedermann (which roughly translates as “everyman”) blew them off; he didn’t believe they would actually do it.
They did; they blew up, burned and destroyed the entire town, including Biedermann’s home. And he wrung his hands about how he didn’t think it would happen.
It can happen here. Nobody is immune. When our police and military are given orders to round up the “violent opponents” of the regime, they will follow orders and carry them out. Don’t put your faith in the “Oathkeepers.” They will eventually be strung up. Just like Stauffenberg, after it’s far too late.
