yes US and EU sanctions on Russia really backfired badly for them.
Now EU is stealing $50Billion of Russian assets to keep Ukraine war going. Which is a terrible decision for any country or business thinking about investing in the EU or US. As US and EU has shown they will illegally break rules and steal your money if they need to.
I think the US and EU know they are economically screwed for decades to come, so stealing Russian money is just an act of desperation.
