Wow, I’m surprised I’ve never heard this before.

Figures. I don’t think that the Ukrainians who were pissed about his suggested “peace deal” knew about this. Either that, or they didn’t mention it. And I remember his article was widely discussed in the Ukrainian media. Maybe if his background was more widely known, his opinion would have been more easily dismissed.

Can someone please explain what he did to be labeled a war criminal?

Genuine question, because I only know this guy as an asshole who suggested Ukraine should give up it’s occupied territories.
