In November 2000 I stood where that photo was taken with a survivor of Dr Mengele's experiments on twins, my late friend Otto Klein, as he recounted to 150 Swiss schoolteachers the last time he saw his parents: https://medium.com/lessons-from-history/seeing-civilizations-thin-red-line-at-auschwitz-with-otto-klein-mengele-twin-survivor-d4cd8c3fb297
It's crystal clear who are the exterminationists in the Russia-Ukraine war: Pavel Gubarev, Russia's "DPR" figure in Donetsk, states their intent towards Ukrainians: "We aren't coming to kill you, but to convince you. But if you don't want to be convinced, we'll kill you. We'll kill as many as we have to: 1 million, 5 million, or exterminate all of you."
The genocidal Ukraine erasure rants of Medvedev, Solovyev, Sergeytsev, Surkov and other Putin media mouthpieces are nearly identical to Gubarev's. https://www.justsecurity.org/81789/russias-eliminationist-rhetoric-against-ukraine-a-collection/
I can say with absolute certainty that my friend Otto Klein, had he lived to see this war that Putin has finally called by its true name, would have sided with Ukrainian's fight for independence and seen Putin's ethno-nationalist Russia as the true inheritor of Nazism.
