I don’t even get how this one is a whataboutism to be honest, you literally stated that war criminals can’t celebrate with Nobel Prize winners and then somebody pointed out that there will be in fact be representatives from countries that have committed war crimes, or more accurately, have fulfilled every qualification for being war criminals but haven’t been sentenced or punished because they control the institutions.
if you’d have said “Russian, Iranian, and Belarusian war criminals can’t celebrate…” then you’d still be a complete fucking dipshit but at least you wouldn’t be totally incorrect in your accusation.
