Also, Hitler had to declare a state if emergency to gain the absolute power the Supreme Court has just handed to the US president.
Suffice it to say, something lile this is impossible now in Germany. The justices of our highest court, the Bindesverfassungsgericht, can only hold the job for 12 years and can be no older than 68. They are also always equally voted in by two different branches of the government and need a two thirds majority for any decision.
Our democracy isn't without faults, but this is probably our strongest bulwark against another descent into facsism.
They're concealing their true nature, and get a bunch of naïve moderates to clean their image. Jobbik did it in Hungary first, it even lead to the radicals splitting out the party under Mi Hazánk Mozgalom (Our Homeland Movement - technically a satellite party and the "bad cops" of Fidesz), and the moderates rebranding as more boring conservatives. Fidesz learned this tactic, and used it to make Trianon Revisionism seem like a "common cause". Gamergate also did it the first round, the second round was just a literal reaction against any kind of inclusivity. The republicans are also doing it of course: Their average voter isn't as evil as it seems, they're just the naïve loyal voters, who think even if things go bad, they can just be removed from legislation. Which is true, but it will be hard if democracy is dismantled like in Hungary, and even then you can't unlegislate ruined lives, the dead from their graves, the lost years people had to endure because of bad laws and no worker's protections.
I think Trump will declare a state of emergency as soon as people will riot against his unjust laws. Project 2025 has something about deploying the military against the population to force through deeply unpopular laws.
