I'd probably need a short sit down if Putin ever appeared there...
However, it's a bit more pressure, 'friends' and neutrals being a bit warier, fewer places he can go. If you're signed up to the ICC, and Putin turns up for a diplomatic visit, you're bound by the treaty that underpins the ICC to arrest him. Neither host not visitor will want that, so he doesn't go places - ever.
His usefulness to other power structures in Russia - and acceptableness(?) to other friendly/helpful states - has been reduced, not by a half, or a third, or a quarter, bit a bit, and it's not about silver bullets, it's about salami slicing, and eventually there'll be a tipping point.
And on the same day that Erdogan announced that Turkey will ratify Finland's accession to the North Atlantic Treaty - What a fucking day, as Putin will have said as he climbed into his gold silk sheets...
