Donald Trump has been officially declared a loser.

You should be concerned if Germany revised all her secondary school textbooks to say the holocaust never happened, Germany did not invade other countries during WWII but merely "entered" those other countries out of justifiable self defense,  and yes, Germany regrets innocent foreigners suffered, but Germany committed no culpable war crimes and is morally no worse than any other country involved in that war.

Furthermore, the chancellor and members of her cabinet took up making official annual pilgrimages to a shrine housing the remains of hermann goering, Wilhelm keitel, and Heinrich himmler,

and Germany just named a major warship Bismarck, after breaking with long practice of not reusing names of major warships from WWII.

One of those things is not like the others. Or did I miss that Bismarck is a particularly controversial historic figure compared to the average?

Not the chancellor Bismarck.   The battleship Bismarck. If Nazi regime didn't name a battleship Bismarck, it would likely be uncontroversial for Germany to name a warship after the chancellor now. But the Nazis did and the battleship Bismarck is identified almost as an icon of the militarism and naval menace that defined Germany in popular perception of WWII. So for Germany to name a modern warship Bismarck would assuredly be controversial.

If in the context of brewing protests and controversies about other actions Germany took and is seen to be aimed at reviving a militaristic past, germany were then to add to the controversy and name a new warship Bismarck, it would most certainly be seen as a further confirmation of the fears raised by those other actions.
