You are missing the point. But lets assume for a minute you didn't join the military assuming it was going to be rainbow farts from gilded unicorn assholes. In EVERY single instance of outrage you expressed above, I can pinpoint a near EXACT equivalent that happened in the US GWOT. Mishandling prisoners of war. Abu Ghraib, 2003. Striking hospitals marked as shelters? Doctors Without Borders, Kunduz, 2015. Raining artillery down on residential neighborhoods? al-Aghawat al Jadidah, Mosul, 2017. Raping and pillaging Ukranian villages? Mahmudiyah Iraq, 2006. I could name half a dozen for each of these actually but those were the best specific examples that most mirror the circumstances you point to above and as I said in my original post, its going to be really hard to pin some of these because Russia doesn't have access to advanced aerial sensors or PGMs that we do (and they are not required to). Futhermore, Zelansky muddied those waters further by giving every civilian in Ukraine a rifle and telling them to go out and kill Russians. I don't fault him for that, this is a war of survival for them, but recognize that makes it really hard to throw charges at Russia, charges, not accusations, and make them stick.
More important to the overall point though, you lack the nuance of how LOAC is applied, where it hails from and the international audience it caters to. You brought up the Hague. Did you know that the United States of America (the country you said you still believed in) is actively sanctioning the ICC and has placed entry bans on ICC investigators tasked to investigate US war crimes in Afghanistan and Iraq. Ever ask yourself why that is? Ever ask yourself how the news stories about the incidents I outlined above were portrayed in the rest of the world? Ever open up a Pakistani newspaper article on drone strikes?
This is just silly. You guys just want to chock everything up to Putin apologetics and in reality i'm just telling you how shit is going to play out as I see it which is that Putin has sufficient fog and noise in Ukraine to effectively conceal a case against the state for war crimes based on Zelansky's decision to arm a civilian populace which massively distorted any cases against distinction and the lack of advanced targeting technologies, mainly sensors and PGMs, which allows Russia greater leniency and presuming proportionality. Just War Theory makes it pretty clear that combatants are innocent of Jus-ad-Bellum and therefore no matter how idiotic or stupid Putin's reason for entering Ukraine is, nothing justifies the extrajudicial killings or Russian POWs that are presumed innocent unless tried and found guilty of war crimes.
If someone understands something better than you don't just dismiss it as propaganda, ask them to explain it. I can write pages on here about LOAC, Just War Theory and the Geneva conventions. If you were a shooter at some point, and you did some shit that bothered you, you probably talked to a Chaplain and a JAG a few times about this stuff, and they probably gave you some things to read, and you probably read a shit ton about it because you wanted to sleep at night. But hey man, what do I know.
One last thing, Russia is not winning the information space right now. Ukraine is. And if you don't believe Ukraine is targeting American and Western European citizens in that information campaign, you are completely naive. And they are not doing it because they want to "be our friends" or "help us lead the free world." They are doing it because they are acting in their own country's interests, as ALL states do. There are "reasons" we are hearing very little about how the snake isle defenders suddenly ended up in Russian custody, what is happening in the inner ranks of the foreign legion, and how Russian prisoners are being treated in Ukraine. If we go balls to the wall break all hell lose against Russia so be it. But lets make sure we are doing it because its in our interests and not because its in Ukraine's interests.
