confiscating money is much bigger deal than you can imagine. Russia and the EU are not officially at war and just taking money because you can is a serious violation of fundamental rights.
Yeah rules apply only on one side it seems, russia confiscated western planes, factories etc. worth tens of billions. I'd say eye for an eye is the only strategy mafia state like russia understands. That and rule of stronger, bigger dog fucks weaker, as russia tends to frequently do.
Afaik principal was not confiscated.
What is violation of what rights?
