What's the craic with this?
Not sure. The "evidence" either way is sketchy. The Linkedin posts could be done by any staffer and are old pictures so are not confirmation of Cloutiers well being. Despite this I suspect that this is a rumour. Devastating if true and I would not be entirely surprised.
Whether Cloutier has been captured/trapped, it is now explicitly stated by Zelensky(Under NATO orders?) that they want to trade to get 1,000 trapped forces out of Azovstal. To this end they have paraded arrested opposition politician Viktor Medvedchuk (handcuffed and dishevelled ) on TV.
Ukrainian forces are surrendering en masse, tens of thousands caught in a cauldron in Donetsk but these 1,000 or whatever trapped Nazis in Azovstal are causing apoplexy to NATO countries for reasons yet to be explained.
We will see soon enough but I expect that there are NATO "trainers" and operatives there.
