Not so hidden.
Remember, there was only five years of “de-Nazification” of Germany, three performed by the USA and two by Adenauer (or so he said); then Adenauer declared the process “over” (not “complete”, take note).
And remember all the reports of neo-Nazism mostly in the east once reunification occurred?
De-Nazification basically involved dumping a bunch of Turks and other Turd-Worlders on Germany.
although it would seem very remote, one can never say never. It seems anti Israel sentiment is still pretty strong, actually in several parts of Europe.
