> The parallels with current political movements are astounding. Fake news, discrediting experts, ignoring protocols, validating xenophobia, using disasters to grab more power - we've seen it all before.
I'm just listening to the "Rise and Fall of the Third Reich" audiobook; a bit dated now (written in the '70s) but also written by someone who was in Germany during the whole time. There are a lot of parallels, but according to him, there are a lot of key differences (caveat -- haven't independently checked these characterizations):
* Germany did not have a strong democratic history; unlike both England and France, which had strong movements towards democracy hundreds of years before, Germany was a functional military dictatorship up until the end of WW I. Hitler could openly say that democracy was a bad idea, and lots of rank-and-file Germans agreed with him.
* Germany had a very strong army that was authoritarian, more or less an independent political entity, and sympathetic to Hitler's aims
* Germany had a very biased judiciary. While leftists were sentenced to death for treason for simply reporting violations of the Versailles Treaty, Hitler ended up spending only 9 months in jail for actually attempting a violent coup. This wasn't just because Hitler was popular or charimatic: loads of nationalists / authoritarian rightists had similarly soft punishments.
The US has a strong cultural affinity for democracy; the military is not, at the moment, sympathetic to a dictatorship; and while according to some reports, some police departments are more sympathetic towards right-wing demonstrators than left-wing demonstrators, the judiciary is not.
In other words, we have a lot more institutions that would need to be subverted before we were in the kind of danger Germany was in the 1920s. Still, better to be aware of the dangers and do what we can to oppose them sooner rather than later.
