USA is on the brink of an authorian collapse.
It’s easy to disregard it as a joke, but it is no joke. This is how Hitler came into power: people said exactly what they say about Trump - and nobody got off the porch.
It’s something worse but unseen: it’s authoritarianism on display when Trump says things like "12 more years". It's intent, not a joke. North Korea, Iran, Russia, Saddam, Gadhafi, Iran’s ruling mullahs come to mind.
Kids in cages, 80% living from paycheck to paycheck, tens of millions unemployed and facing eviction, 180000+ dead in the out of control pandemic (which is a purposely done thing to create chaos, looting and rioting every night with people getting killed), kids in cages, military in the streets, The ruling party pretending this all doesn't exist.... and the ruling party displays itself as perfect, above the law, fighting Gods battle of good vs. bad...
Next up, after they steal the election and kill the constitution is that people will start disappearing if they say the wrong thing. They already have the military in the streets and he has enough of "his judges" in place - including the mail.
Why are people rioting and looting at every chance? Well, right now they can. Again: nobody is getting off the porch, and soon there will be no more porch to get off of because in the streets are the secret police.
Well then.
Your path to get there is a pot-addled and confused one, but you are correct in pointing out some similarities. Except that Trump is part of an established Party within a failing Republic. So he would be more like Hugenburg in the German National People's Party, or the main conservative party.
So, there is no 'Hitler'. Trump is part of the Elite. Hitler was a Corporal who was from the equivalent of the American middle middle-class. So the 'American Hitler's' father would be a GS employee, but not of high rank because they lack education. Say a GS-11 who worked at the Post Office (US civil service ranks go to GS-15).
In any case, there would also have to be a two-decade period of open political assassinations and open rebellion. Not burning up a Macy's, actual armed troops in the streets every couple of years, with the conservative veterans, the Friekorps, putting the Commies down.
There would also have to be widespread poverty and hunger among the Upper Middle Class. The US's problem right now is an overabundance of food and too much electronic entertainment.
Also, the infamous Inflation. The US is still creating wealth at breakneck speed for a mature economy, after 2008 it was only a couple of years before people got back into the Mortgage game, and most families make $100,000+ in 10-15 years on their homes. Meanwhile in Germany, people were carrying their money to the market in big flour sacks. At one point, it was possible to start a day job for a wage which wouldn't pay your trolley fare home that night.
You would also need millions of jilted Veterans, as in the entire surviving male generation between 45-75 years old being hardened combat veterans who fought in perhaps the most atrocious conditions in human history. The US meanwhile is getting out of 19 years of wars which yielded about 7,000 deaths total, with less than 50,000 people seeing even a brief stint of high-intensity combat. And after their patrol down the airport runway, they came back to base and had a selection of KFC, Taco Bell, Md'Ds, or Subway to eat. Then TV and the weight room. Maybe a BBQ and Robin Williams would show up and do a set.
I mean we're not really close man.
