Hitler tried building a “firewall” around Berlin to stop the Soviets, IIRC.
And the result was that everything and everyone who didn't recognize/ couldn't get out of the path of the demonic strategy of burning all the evidence turned to ashes, leaving satisfied a now sated Satan, giddy with delight at the carnage and hatred left in his wake.
The Left is under Satan's control, having succumed to his wiles, they will see only green meadows where there instead the smell of sulfer burning prevails.
