I have the same impression, just old bitter fart and shadow of a man he once was, entrenched in his untouchable position, throwing childish deadly tantrums on a nation that decided to stood up to him as one.
An idea - even if they laugh on ICT in Haag, what if there would be international arrest warrant on all those sanctioned persons including him, no diplomatic immunity? Meaning they can't travel most of the world, forever. Just a nuisance maybe. but proverbial death by thousand cuts starts somewhere. And remove russia from permanent UN security council for the duration of 'special operation', since they just veto everything now.
