The 1930's Third Reich playbook versus 2025 USA:
Get in bed with the biggest companies -Krupp, BMW, etc (USA: Musk, et al)
Control the media/propaganda (USA: Musk, Zuckerberg, threats/lawsuits against mainstream media)
Lie, lie big, lie often and the lie becomes truth -straight out of Mein Kampf (Trump tells thousands of lies, Stop the Steal being foremost)
Eliminate opposition - murders, drive into exile (USA lifts Secret Service protections, fucks with voter suppression, reverses equal rights)
Identify a scapegoat(s) and propagandize accordingly - Jews, gypsies, intellectuals, homosexuals, communists (USA: pretty similar, note comments about 'radical left', colleges and gender)
White caucasians rule, everyone else is inferior (USA: ditto)
Blame state of economy on other countries (USA: apparently Canada, Mexico and China are responsible for US having the world's richest economy) BTW: Inflation was caused by all that free money that Trump sent out during Covid, same as every G7 country.
Threaten nations to get concessions - Czechoslovakia, Poland, Saar Valley, etc the concessions didn't work Hitler kept taking more (USA threatens democratic nations with economic and military force)
And just like in 1930's there were appeasers, folks saying the Nazis weren't really serious, and folks thinking they were safe; until they weren't. Facism is a slippery slope and the velocity increases over time unless its shut down.
That's just scratching the surface, hopefully someone has or will do a book examining the parallels in more detail.
