Tolong jelaskan mengenai Stasi smear campaign dari Konstantinos Karamanlis

In 2001, former agents of the Eastern German secret police Stasi, claimed to Greek investigative reporters that during the Cold War, they had orchestrated an operation of evidence falsification, in order to present Constantine Karamanlis as having planned a coup and thus damage his reputation, in an apparent disinformation propaganda campaign. The operation allegedly centered on a falsified conversation between Karamanlis and Strauss, a Bavarian officer of the King. They also alleged that a photograph of the former New Democracy leader Constantine Mitsotakis standing next to a uniformed Nazi officer, that had been repeatedly published by the PASOK-leaning Greek daily Avriani, was in fact a photomontage fabricated in Bulgaria. Their disclosures have not been challenged to this day.
