At a 2008 summit, NATO stated that it would attempt to expand to include Georgia and Ukraine, despite Russia having stated that NATO membership for those countries was a red line for them. Georgia was immediately invaded by Russia in response. Imo this makes it clear that NATO membership for either of those countries was so unacceptable that Russia would rather invade.
If we assume that Russia (and Putin in particular) is acting violently and irrationally like a wild animal, why did NATO continue to agitate Russia when the only possible outcome would be violence? Surely a neutral or even Russia-aligned Ukraine would be preferable to a war-torn Ukraine? This is proof that the US and NATO don’t care about the average person actually living in Ukraine, and indeed don’t care about the Ukrainian state beyond it being a useful (and profitable) proxy against a geo-political rival.
To be clear, I’m not excusing Russia here, but geo-politics aren’t about what’s “fair” or “right”, and if they were, the US would be a global pariah.
