Just look at Austria, very rich but obviously Russian run EU country. (latest prime minister got fired by Russians even though Russia cyberarmy helped him win the elections. They decided he was no longer as compliant, so they leaked data many years after elections, Russian scandals several years before that etc.). Raiffeisen bank in Austria, basically launders money for Russians over the last several decades, with no consequences to the chief officers.
Hungary is another good example.
Another Austrian neighbor, Croatia, not rich, and less influenced by Russians, had one of the biggest scandals ever when the biggest privately owned company in the Balkans (owned by a Croatian), that employs a massive amounts of Croatians, went bankrupt and could have been acquired by creditors (Sberbank and VTB Bank). I guess there was not enough Russian influence in politics and Croatian government put a new law immediately, so that this kind of takeover does not happen (Croatia nationalized the company).
Russia has quite a large reach into EU.
