The Sam Lane in that storylane was Hitler in all but name. Also that Sam Lane had no idea that Superman was his son-in-law. Nor did he have a personal relationship with him. And there were no grandkids. That Sam Lane was nothing but an evil villain. For one thing he masterminded the murders of the scientists who ran the Cadmus project. That storyline portrayed the U. S. military as being composed of nothing but genocidal warmongers. It's very possible that is one of the reasons the Super titles were losing readers at that time. The panel you posted here looks more like one of Hitler's rallies. The only thing missing is shouts of sieg heil.
