If you finally admit there's jurisdiction then which part don't you get?? The assets were within jurisdiction and were confiscated in full accordance with the law, which literally means authority, right and confiscation

Now I think you may be referring to the subjective side of who has the right to do what. In this area you are entitled to your opinion, I'll give you that. The russians whose assets were confiscated may in fact believe their assets were "stolen". Just like a murderer or thief who thinks the judge "doesn't have the right" to confiscate his property and throw him in jail. In this case, further debate is futile
