Just like when Hitler let Allied troops be extracted from Dunkirk.
I just love how the media is uncritically repeating Nazi talking points. And this is the same soldier that the MSM has been showing giving updates on Mariupol. Note how he has the Azov patch on his chest covered. Previously he'd had it out in the open. Of course its all moot when there's another soldier right next to him proudly wearing their Azov patch on their sleeve.
He sure didn't seem to hesitate to take up the whole "we'll keep fighting forever!!" Line that just so happens to be really convenient for America and absolutely disastrous for Ukrainians. Wonder if he got a good deal out of it or he's just that much of a shithead.
Based on what we know of him, I would hazard to guess the latter.
