I think it was actually Hydra, pretending to be Nazis, who were pretending to be Robert Byrd, whose brain was secretly inserted into a robot (right before he died) called the Mechanical Kleagle. He led a team of SpecOps Klansman to take down CHAZ.
Equally as likely.
Bravo, you figured it out!!!!!!!!
That’s quite the satirical imagination you have there!
