Of course, I worked at the International Criminal Tribunal for Rwanda. I was involved in the first genocide prosecutions at that tribunal. In that case, we were talking about killing on such a large scale that genocide was established beyond doubt.
The other example that may be of interest is the case of Srebrenica in the former Yugoslavia. The International Criminal Tribunal for the former Yugoslavia found that there had been genocide in the case of the killing of military-aged boys and men from the Muslim community in Srebrenica. It was a somewhat controversial conclusion that has been challenged by some theorists, but it is another example of a case of genocide.
That's why I don't take a position on Ukraine. We have to be careful. That said, there are still elements that need to be examined.
