> hence my point that Ukraine behaved irresponsibly with regards to avoid Russian agression
Or in fewer words, your blaming of the victim. Don't act as if it wasn't entirely Russia's choice to invade, without any comparable provocation. It's not Ukraine's job to placate Russia. Avoiding Russian aggression is Russia's job. There is no guarantee that Russia wouldn't have invaded anyway even if Ukraine didn't pursue NATO membership. (The threat of this is why they wanted to join NATO in the first place.)
