I would say it's valid to dislike this as an oversimplification. It's a super complex series of unintended and intended consequences, bad ideologies, and terrible behavior generally.

They say war is a failure of imagination, and it has been increasingly hard for either of the belligerents to imagine peace.

I think the only humane view we can take as bystanders is to support asylum seekers as much as possible and condemn war crimes no matter who does them. Most people are just caught up in the gears of history. Nobody deserves this.
