>I get the impression they are still pissed about that.
Well, that makes not a lick of sense. A war took place 8 years ago, mostly died down, people lived in relative peace, and now Russia starts a war of aggression on a whole new scale, rains death from the air, unleashes its troops to commit mass murder, takes thousands of civilian lives because "they are still pissed about that"?
And pissed about what? Its own actions? Russia instigated a war in 2014 by creating a proxy army out of thin air (and funding, arming and manning it with its own soldiers), then just straight up invaded in August of 2014 with its own regular forces. They routinely bombed civilian areas without any regard for the civilians still in them, used civilians as human shields, positioned MRLS launchers inside apartment blocks, etc.
I don't know what happened in the airstrike you brought up, except to say that by July 2014 Ukrainian air force wasn't used much due to Russians bringing in their SAM systems, such as the Buk that shot down MH-17 just two days after this article. Especially in 2014, Ukrainian army was a rag-tag outfit using Soviet-era tactics, and they did occasionally hit civilian areas in situations when a more modern army would be able to avoid it. There were instances where you can say they tactics did not sufficiently account for civilians. There were many more instances where Russia proxies used civilians as shields with success, however, and the Ukrainian military showed restraint.
Either way, at the end of the day the blame for wars of aggression has to lie with the aggressor, not the victim that's defending itself. This was true in 2014, and it's sure as fuck true in 2022.
Not even gonna get into that whole "NATO expansion" clusterfuck. If you think a fascist dictatorship should have veto powers over which defensive alliances its democratic neighbours voluntarily choose to join, there's not much there left to discuss.
