Unfortunately, I think you've made a false dichotomy here, resist and be harmed in the fighting or surrender and be preserved. No, there will be "surrender and be harmed" as every Eastern European Nation has testified, since today is the anniversary of the invasion of Czechoslovakia by the Soviet Union and Warsaw Pact. Do you know how many people have accused Europeans for being in the payroll of the Americans for wanting to defend Ukraine (or for anything that displeases them)? Give the respect that self-defense is part of one's own self-agency.
There is a very easy way for the wholesale destruction of two countries to end. Russia could stop it's invasion.
The invasion of Czechoslovakia might have brought decades of poverty and misery under the Soviet influence on the region, but at the same time, we're talking about a nation with half a million of people dead, critical infrastructure completely destroyed, an economy in shambles, a demographic crisis worsened and a complete dependence on foreign aid to survive.
To be completely fair, the United States has had a pretty big role in interfering and subverting foreign regimes all over the world. The CIA's constant efforts in replacing democratic governments in South America with authoritarian regimes willing to work for their interests. They did interfere in territory of the Soviet Union as well, ironically they did it in Ukraine as well during that time. Not that the Soviet Union was a harmless victim, but there is precedent for that.
The war should never have happened. In all likelihood, Russia didn't want it either, which is why they were caught completely unprepared for it. They only sent 30k troops to capture Kyiv. I believe they most likely intended to oust the Zelenskyy regime, replace it with one friendly to Russia and keep the LPR, DPR and Crimea as independent puppet states. That's when they got stuck and it was too late to go back. Now the big question is how to end it. Neither side will capitulate willingly, that is a non-starter. There are still rumors of possible negotiations, that Kursk is meant to give Ukraine a bargaining chip in them. The problem is, if things go wrong for Ukraine, if they have to cede land and renounce NATO membership in the end, the question for everyone will be if all the fighting and losses were worth it.
Did Hitler start with camps everywhere? No, it built up gradually. To answer an earlier question it would be disastrous to Ukraine and it's people. That I've heard enough of Russian propaganda towards the "khokhol" that their intentions aren't secret. It could even be said that Communist China is eyeing the results of this war for their own plans. With the return of far-right politics as well in the equation and Russia's attempt to cultivate other such like-minded wannabe autocrats & extremists, I wouldn't say WWII is an unfair comparison.
There's even a lesson from France from this period about the cost of surrendering.
Hitler started with a well defined antisemitic rhetoric, propagating the "stab in the back" claim and blaming the Jews years before he was in power. He published Mein Kampf with outlines of his ideas as far back as 1925. By the time of the war the Nazi party had a grasp on a big part of the German population, plans of going for the Lebensraum and driving the "Untermenschen" away were already known. Likewise, Japan had already started its expansionist policies as far back as the 30s. They were prepared for war. Russia wasn't.
Russia's alignment with other autocratic states seems more like a product of necessity than anything ideological or political. It's not like they have much choice but to make ties with North Korea or Iran, they're not particularly worried about Western sanctions and they get leverage against the West by supporting one another. China maintains its distance relatively speaking.
Russia invaded and deliberately targets civilians, while Ukraine hit military targets with the deaths in Crimea you mentioned being from debris. The scales in deaths of civilians are a difference in order of magnitude. Enough journalists are in Kursk to show difference in incursions.
Ascribing intent to strikes on civilians is pretty difficult when information is unreliable and there is an extremely heavy information war campaign to influence public opinion. I mentioned the strike on the hospital on Kyiv. During a Kh-101 cruise missile attack one hit part of the hospital and killed 2 people. This isn't a small building, it's 130m long and more than 8 stories high, yet the missile somehow missed the main building, and destroyed a small toxicology building. It didn't stop many from stating the attack was deliberate and that the hospital was "leveled".
The more I looked into it the more inconsistencies, omissions and outright lies from the media I found. And that's exactly what bothers me about it. Ukraine uses misinformation and propaganda as much as Russia does, possibly even more, as the media and the public repeat the same information. Stuff like the "Ghost of Kiev" going viral is a good example, a fairly benign lie as far as propaganda goes, but it shows how readily people are willing to believe lies that support their stance. If they're continuously lying to me about Russia running out of missiles, if they're lying to me about the drones being intercepted, if they're lying to me about equipment destroyed, about battlefield casualties, about civilian deaths, if their own analyst from think-tanks like RUSI admit the West believed their own propaganda leading to the disaster of the 2023 counteroffensive, what else can they be lying about?
The problem with comparing what is happening in Kursk with what happened in the Donbas is that the latter was being fortified ever since 2014. The Kursk incursion started with highly mobile, highly trained and well-coordinated troops taking up positions in land mostly defended by border guards and conscripts, because nobody was expecting an attack there. The Donbas is filled with trenches, fortifications and minefields. Every high-rise building in urban areas becomes a fortification. Hence the very heavy artillery barrages, the buildings demolished with FAB strikes and the costly fighting over tree lines and open fields.
Beware, I think you're over-correcting and going from a black-white dichotomy towards muddling in inability to distinguish between right from wrong (and they're not opposites, they're two sides of the same coin). It's a criticism that I had towards the Neo-cons & American Right (ironically enough) as well, that for all their talk of "you're either with us or against us" their mistakes shattered them to the point that they are now one of the most unreliable factions in NATO. Fanaticism burns itself out faster into nihilism than anything more even-tempered.
Maybe. What led me down this road was noticing how much I was being manipulated and the reality being distorted. My view of the world was based entirely on one side of the story and the complexities being ignored in favor of a simplified good versus evil narrative. Let me be clear, I do not support Russia or the invasion, I find it hard to justify war in all but the most extreme cases. I do try to figure out and understand their motivations and be objective about them.
But at the same time I cannot support Ukraine. I support civilians, I sincerely hope they get the best outcome that causes the least of damage for them because they're the victims. I just do not trust the Ukrainian government or authorities. I do not buy for a second the idea that the West is defending democracy and freedom when you have people like Senator Lindsey Graham bragging about how weapons that they've provided are "creating jobs in the US" and how they're "learning about their own weapon systems" while they're tested in Ukraine, or a few months back when he spoke about the trillions of dollars in minerals in the Donbas he wants so much.
But if you think it's a cause worth believing in, I may not agree, but I respect your position.
