Roger that.
As a historian, you might be interested in the history of the Organisation Gehlen which became the Bundesnachrichtendienst.
Also, only relatively recent work was done on the history of the FRG’s State Department and it’s internal workings with old Nazi networks.
To the best of my tiny knowledge, this was fully sanctioned by the US, specifically, and the other Western Allies.
(This does not, however, explain why Nazis are in the German parliament again.)
I think you might be referring to Horst Mahler.
It’s very interesting to see what became of some people involved in the RAF proceedings. Gerhard Schröder was once Mahlers lawyer, Otto Schily lawyer of Gudrun Ensslin, Hans-Christian Ströbele lawyer of Andreas Baader.
ETA: it makes me wonder how the German extreme left of the 1970s, famously speaking and writing in long-wound sentence, would have used twitter.
The current extreme left is in no way on par with the rhetoric abilities of that period.
