Yea ok I researched visegrád 24 and not only are they not officially tied to the Visegrád Group and any other news agency and do not have to listen to anyone, but they are also known for spreading false information and reposting satire as serious news without research. As I said before, no serious German newspaper has posted anything about the "scandal" yet. I can't find the "nuclear files" and all of this seems to be intentional misinformation or bad research.
They do not even link to anything that could hint at a big scandal. None of the links you send lead anywhere important.
