This sounds great at first, but I do wonder how this could affect Europe’s standing with a post-Putin Russia. Frozen assets are a bargaining chip only so long as they are frozen and not permanently confiscated.
In the best case scenario Putin is gone and the EU can unfreeze these assets with conditions to be met by a new Russian administration. Worst case scenario, permanent confiscation shows Putin is the Russian elite’s only hope.
I’m not usually this pragmatic, so I’d be happy to be wrong about this.
