So you genuinely think forcibly annexing the most economically lucrative part of another country right out from under them isn't what probably caused most of these mid 2010's issues in the first place?

Furthermore after carefully cutting crimea away in 2012 you think that it's completely normal to handle a separatist revolt on your border by attempting to subjugate the entire country over some militia with poorly thought out ideals.

If you can't see this as an obvious bid by Russia to reclaim Ukraine, you're blind. War is a terrible thing but Ukraine itself hasn't actually done anything besides fight to not get vassalized by a land hungry superpower that would have no reason to stop at Ukraine when they were done. That's kind of the reason why they have global support right now. No one wants Russian Boots knocking at their border.
