I am considering the absolute impact on those affected, which is the most relevant for this discussion. Millions are not "a few". And it's absolutely unnecessary, the aggressor has always been in the position to pull back and leave (or not attack at all). Everyone but _a few_ war profiteers suffers from war, because it requires hours of work (weapons) diverted towards destroying other hours of work (cars, houses, infrastructure), occupying workers' time by ordering them to kill future workers, all of which could go towards increasing production instead of decreasing it, which does affect global markets and thus people globally.
Had? Ukraine still has the option to capitulate and give up its territory, what kind of argument is that? Separatists who take up arms are a fair target, they are the ones violently changing the status quo. When both sides kill civilians in a war started by one side, that side's further escalation is not at all justified by "killing ppl of donbass", so let's not manipulatively paint a "both sides" picture as if there isn't a huge difference
