The USA is distracted with treats. It's economy is the imperial core of the planet. That fact affords Trump some time before the masses realize what's going on.
Remember that the Nazis made the economy temporarily better for the in-group. They actually allowed socialist benefits for the German workforce before clamping down on that during WWII.
Trump isn't making the economy better for anyone though. He's screwing everyone over, and channeling that hate towards anything else but him and his base.
Just as we've seen with Charlie Kirk's murder and Candace Owen's conspiracy theory to blame it all on Israel, the Right can fracture very easily. I don't think this Admin will make it to the height of the Nazis. Their own incompetence and marriage to the rich will sew the seeds of their demise. Of course, anti-fascists throwing wrenches in things doesn't hurt either.
