It was carnival. There was a lively mood at the Rheinmetall Group's headquarters when news burst in that suddenly caused disillusionment: The US financial investor Guy Wayser-Pratte, known for his less squeamish methods, announced his entry as a shareholder.

It would take 20 years to actually get there. Namely now - this February.
