"Stern" (No. 50, 1970) published Sven Simon's (Axel Springer Jr.) iconic picture of Brandt kneeling before the memorial to the Warsaw Ghetto Uprising on 20 Dezember 1970 on a double spread. It was accompanied by an interview with Brandt's Polish host, premier Jozef Cyrankiewicz, with whom he had that day signed the Treaty of Warsaw. At the same time, "Stern" sought to discredit the rival conservative weekly "Quick", which in opposition to the Treaty had published material from its secret protocols. It accused the magazine's editor Hans van Nouhuys of having been a double agent, at one time in the employ of the East German "Stasi". "Stern" successfully withstood the charge of defamation.
