Many politicians and regulators have ensured cozy obnoxiously paid executive and advisor contracts on this affair. Not counting the 1.9 billions EUR missing, but that's probably already parked somewhere in real estate. It's like Panama Papers - a solid scandal... locked in a concrete basement.
I just skimmed through the wiki page and well
Involved are: members of austrian secret service, russian secret service, german politicians on highest level, german biggest media empire(Axel Springer) ... and one of the villains is now supposed to be in russia?
I think there are many pieces missing in the puzzle.
