NATO didn’t exist in 1939.
There are few parallels here. Germany was building for war as early 1935, but because he was the darling of capitalists and ruling classes in the West, all warning signs were ignored and he was given what he wanted until it was absolutely too late. Three was more worry about Russia and expanding Bolshevism, so ruling elites were happy to use Germany as a bulwark against that perceived threat.
Putin, on the other hand, has been an official enemy since at least 2008 when they invaded Georgia, which again had everything to do with NATO encroaching on Russia’s border.
Official enemies get a very different media treatment to official allies. Allied dictators are “reformists”. When they invade a country, it’s to liberate some people, or because of legitimate security concerns, or because some offical enemy is in power and poses a threat that needs to be removed.
Official enemies are always dictators and tyrants, even if democratically elected. They are always aggressors, always posing threats to the West (even if they’ve small military budgets and don’t invade anyone), and there’s always calls to go to war with them in the name of freedom and democracy.
No one really knows the mind of Putin, and even though this invasion surprised a lot of people (it was regarded as a stupid move to make, as he’ll now likely be bogged down in a lengthy and costly insurgency) he’s so far committed a fraction of the crimes that a typical US President does within a couple of terms, and it’s absolutely nothing compared to what Saudi Arabia, our dear ally we’re supplying and providing logistics for in the middle east, is doing to Yemen, which gets practically no coverage in the media.
I would suggest to believe absolutely nothing you see or hear during a war. You don’t know the sources of any images and videos you see. You don’t who fired what or who shot what. It’s pure distilled propaganda.
If one thing should be obvious, it is that there’s a concerted push to escalate the war and to normalise the idea of a broader and more devasating conflict. I’ve already listened to journalists blithely talk about surviving nuclear attacks, and how we should have a ‘No Fly Zone’ over Ukraine, which basically entails direct military confrontation with Russia. I’m listening to fucking madness and even read some of it above.
