alt Hacker NewsAccording to AP News (https://apnews.com/article/international-court-sanctions-tru...) at least one judge had his bank accounts closed. So it's not just your own government who can debank you in Europe.
Of course in this judge's case there might still be some banks who are willing to work with him even at the risk of getting sanctioned as there weren't language in the news that he was completely debanked which I assume they would highlight if it was the case.
The main problem IMHO that a bank access not seen as a right. Even Russia which is neither powerful (unlike the US) nor an EU ally can de-bank Russian critics living in the EU (and other places) by reporting them to FATF. AML is ripe for abuse.
