Apparently, the prospective Kaiser had the idea that Hitler would've brought him back to the throne and initially supported him because of that idea. If he wasn't wrong on that front, would it actually have been possible? Was Hitler actually capable of bringing back the monarchy? Would there be any noticeable difference in how Germany would've been like aside from having a royal head of state? Would the personality cult still be there? Who would the oath of allegiance be given to? Would there still be WW2 or could the Kaiser have restrained Hitler?
