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.
I've seen Neo-Nazis try to spin Dunkirk as Hitler being kind and wanting a Treaty with Britain.
