None of these idols make any sense, why would you focus on an Empire which relied entirely on everybody being too busy to deal with them and think they are worth shit?
Germany was a roughly stitched together group of vaguely similar ethnic groups which didn't speak and write in the same language until the 1800s. Seriously, Germans would speak something like Dutch or Czech and write in "Standarddeutsch" - and it's only slightly better now, in 2021.
The fact they managed to pull off a nationalist Empire should tell you that all Whites, worldwide are pretty much interchangeable with one another.
Japs are not worth looking at even briefly for advice - it isn't especially impressive, most European states have similar crime levels among their White populations - especially those who don't have many immigrants, many drugs or many ongoing ethnic conflicts.
The Jewish Problem was solved in Europe by 1948 - the Germans had succeeded mostly, and those who survived found that in most of the continent, the locals were sick of their shit - outside of Britain and France (even Ireland was sick of their shit) they found they couldn't permanently settle since people would burn their houses down, so many ran to the USA and to British Palestine. After terrorising Britain and setting up camp in Palestine, Israel was created and immediately, the Arabs were sick of their shit too.
For whatever reason, Americans seemed to love the taste of Jewish cum and then, using the USA as its golem, began to smash and pozz its way across Europe, starting with Britain and France, then Germany, and continuing to the point where even the USSR started to consider themselves as the only hope for the White race (Brezhnev)
