Anyhoo, the same 'rehabilitation' is unlikely to occur for Hitler, since the German people themselves have, overwhelmingly, rejected Hitler's historical legacy and have (unlike Mongolia) proven themselves to be a successful nation even without that historical legacy.
That seems to be a bit short-sighted.
It has been less than a century since the conclusion of the war and its immediate consequences are still very much ongoing, in Europe, East Asia, the Middle East, etc. The federal republic is, as I'm sure you can objectively appreciate, a puppet regime of NATO and outsiders; German soil is still occupied territory. It's a bit irrational to conclude what the feelings of people will be far down the line. Neoliberalism will fall, just as any other ideological hegemon in history, and when it does, the people not just in Germany but everywhere else, will view politics, morality, and history through an entirely different prism.
I can speak for those in the areas surrounding my cousins and extended family in Sachsen; what people will say in certain settings is entirely different from the image that is projected of the broader community on the media. Denazification was a brainwashing process; this has to be understood. And when the military and economic power of its architects runs out, so will the anti-national ideology and benefactors of the current regime which is a dishonorable one for any German man, woman, or child to live under.
Finally, what has to be understood is that most of the people now living in the country were not alive for the war or its preceding years. The overwhelming majority of people in
any society, throughout time, will believe anything if A)Their parents raise them to believe it; B)It is taught to them in primary schools; C)It is reflected in the media; D)Most others they speak to in society believe it.
Again, the belief you're referring to (rejection of the legacy of NS Germany) is an outgrowth of this. Most Germans alive today were born into the situation and know only what they have known from birth. This doesn't make the present situation any less temporary than the first round of National Socialism proved to be.
Germans, even those of an illiberal and fascist mindset, in my experience reject Hitler completely because his bungling destroyed Germany and impoverished the German people to a greater extent than happened after the First World War.
The consequences of the defeat cannot be blamed on the German leadership. This can be said about any war in history if one's horse loses (that there are terrible consequences), but it never negates the value in fighting.
Hitler called the German people cowards in the days before his suicide and said that they deserved destruction since their defeat at the hands of the Slavs meant they weren't fit to lead the Aryan race.
The first thing people fail to understand about Hitler both as a person and as a politician is that his ideology had to do with some much more than simple German nationalism.
