Ah, the familiar and long-debunked "Ukrainians are Nazis" rhetoric. It was first put forth by Stalin after WW2, as he found it convenient to draw imaginary parallels between Ukrainian Nationalism and Nazis, as an excuse to persecute Ukrainians who dared have a national identity. It then re-emerged in 1987 in a Kremlin Sponsored book by Canadian Communist Douglas Tottle as part of an effort to deny Russian culpability in the Holodomor. It was pulled out of mothballs in the 2010's by Vladimir Putin as a way of justifying his annexation of Crimea, while Democrat Party (jointly-owned by the CCP and the relics of the KGB) parroted it as a way of discrediting Trump (who was at the time arming Ukrainians against Putin and bombing Russian bases in Syria, despite the Left's attempts to claim he was a Russian puppet) with the "he is arming neo-Nazis and white supremacists" garbage that they usually fall upon when lacking any other meaningful commentary.
And now, armed with photos like this one wherein Russian troops pose in stock Ukrainian costumes with home-made props, it is echoed by American Liberals, the faithful lapdogs of Neocommunism everywhere. Well-done, "Komrade." You've served your Russian boss (and his Chinese master in turn) faithfully, with a photo that a handful in the West might actually be stupid enough to believe.
