Are you not aware that the Wagner Group is so named because of the neo-Nazi sympathies of Dmitriy Valeryevich Utkin, its founder?
As for the cartoon being simplistic, this is not a war between angelic Russia and a neo-Nazi regime in Ukraine. It is war between Russia and Ukraine pure and simple. Putin has publicly proclaimed that he does not recognize Ukraine as a legitimate country and desires that it be reunited with Russia. Ukraine has every right to resist.
From what I have deduced, the term “Nazi” is being equated to patriot. Those who love their country and willing to give their lives defending it are being called “Nazi” by those who want to denigrate Ukraine. Frankly, I admire the Ukrainian grit in taking on one of the strongest and fiercest armies on the globe.
