eighty years later, in Germany is still trying to live down their shame

Yet, it seems many Germans are prepared to go down that same road with the AfD.

well except all the Nazis in Germany that were brought directly back into:

• Official posts within the federal government and its ministerial cabinets
• into the upper judiciary and magistrates
• into local governance
• elevated and hired into immense wealth in industry and finance, or just kept where they already were in industry and finance
• hired into forming the Nazi core of the West German intelligence and secret police agencies (which would become today's German agencies) under the protective auspices of the OSS/CIA; who made extensive use of their networks of executioners and collaborators to prop up US-backed dictatorships and cartels and use as anti-communist stay-behind guerilla terrorists by the CIA and NATO (and brought into the CIA and FBI themselves, and into MI6 and Mossad)
• into German academia and universities as faculty and professors,
• to write western history books at the behest and with support of the US Army and OSS/CIA to sanitize themselves
• all those hired into NATO and into the EU
• into positions of power in West Germany (and all the NATO countries, helping in and helped by Gladio violently purging the communists) in such saturation and such impunity that it caused the formation of left wing militant groups that would assassinate and kidnap them.

but other than all of that though!

(And that's not even mentioning the Nazis and collaborators which made up the origins of Radio Free Europe/Liberty, the "Victims of Communism Foundation" which grew out of the fascist-filled anti-Soviet "Captive Nations Lobby" headed by OUN-B Nazis from Ukraine, and all the Operation Aerodynamic, Operation Paperclip, Operation Sunrise, Operation Beladonna, Operation Lynx, etc etc.)

uhh, most of germany yeah.

Maybe. The US would have to first begin to feel actual shame about colonization and slavery though, which hasn't really begun in earnest.

I don't know if the US has the capacity for feeling the weight of its true guilt.

Half of Germany doesn't think it was that bad and wants to repeat it. Or has at least nothing against a repeat

Please remember that the opponents of trump/MAGA are currently enacting their own Holocaust.
