In every war since WWII, the enemy is always painted in the image of Hitler. I am sure there's a lot of horror going on in Ukraine right now, as in every war (do you know of any war that's not pure destruction and horror?)... but to say it's close to the horrors Hitler committed is, in my opinion, grossly failing to see how the motivations, tactics and methods involved differ enormously.
Until I see gas chambers being used to kill Ukrainian civilians in mass, and innocent people being rounded up and burned inside buildings like the Nazi did, I would say we're still luckily very far from the same level of cruelty. And I pray to God we'll never see that kind of event again.
International organizations claim the number of dead civilians so far is around 400, which is in line with a full scale war where civilians are killed in the cross-fire, as horrific as that sounds.
For comparison, the USA invasion of Iraq caused around 5,000 civilian deaths in the initial few months [1], so it was actually likely much worse than Ukraine! Would you compare that with Hitler as well?
Early days yet. If you check my comment, I said he's replicating the run up. It remains to be seen whether he will be allowed to commit genocide but he's written about restoring old Soviet borders and he cannot do that without going against the wishes of 10s of millions of people. Maybe 100s of millions.
The comparison to Hitler is inevitable not because of death camps or body count, but because the foreign policy of Russia today seems to be on the same trajectory as the foreign policy of Nazi Germany prior to WW2.
Germany took Sudetenland from Czechoslovakia on the grounds that it was populated mostly by Germans, who were being oppressed by Slav-dominated government. Russia took Crimea from Ukraine on the grounds that it is populated mostly by Russians, who are being oppressed by the Ukrainian-dominated government.
Germany subsidized a Slovak separatist movement in Czechoslovakia, culminating in the declaration of independent Slovakia, which promptly became a German puppet state. Russia tried to do something similar with Donbas separatist, although it wasn't particularly successful.
Then, at last, Germany invaded what was left of Czechoslovakia, with intent to fully annex and absorb it. We're now watching Russia do the same to Ukraine.
Russia is firmly in Nazi territory right now.
