The EU themselves "froze" (essentially confiscated) Russian assets, both state and private.
This is a very weak punishment for what Russia is doing every day.
It is surprising to me in a bad way that someone thinks the relationship between the US and the EU (who have traditionally been allies) has become so adversarial that someone would compare it to the relationship between Russia and the EU.
The comment was: the EU should expect the US to hammer them the same way they hammered Russia.
And my point was, that would be a significant course change because for the US & EU to be like Russia & EU would be a significant change.
That was my point. I hope that is clear now.
The EU have very deliberately avoided actually confiscating Russia's money. It is sill there, and (much to the annoyance of those who do want to actually confiscate it) Russia can have it back as soon as they stop their illegal invasion of Ukraine.
Closest the EU got to actually confiscating that money is, in fact, a loan such that if the peace agreement fails to include reparations then EU nations cover the loan but everyone's hoping Russia agrees to reparations so they don't need to.
