this is not true, war crimes exist and have legal definitions, even in WW2 people pushed back on some things their government decided to do, like firebombing large civilian centers
hospitals and water facilities are easy examples, which Israel is very guilty of violating in recent years
unless we're talking about, say, japan, where the firebombing campaigns killed more civilians than the two atomic bombs :P
WW2 is arguably bad example because everyone was committing crimes against humanity, worst thing humans ever did do, and today we're doing a lot of the same things that got us there
The parent said "public outcry saw this tactic end".
To my knowledge, it didn't end. That's why I asked for sources and explained how Dresden happened at the very end of the war, where they still employed the tactic, that OP said was ended because of public outcry.
That is why total wars are distinguished from a normal war. The concept that "all civilian infrastructure supports the war effort" is used in a total war to justify firebombing civilians.
proclaimed by who? Even the "international order" would disagree, as Yandex Cloud wasn't providing their services to any military companies per my knowledge.
Yandex Cloud was bombed symmetrically. Ukraine made no attempt in targeting MSK-IX, which could be a real military target.
1) or government organizations?
2) why would you have any knowledge of who Yandex's customers are?
