It’s not like Ukraine could just tell Putin “sorry, we don’t consent to war” and have him be unable to attack them anymore as a result.

Tell that to Putin.

So what exactly was the plan last year when the russian assholes crossed the border to Ukraine and started a war with weapons?

Weapons of war are the ONLY solution when you’re being invaded by a hostile foreign power. It’s great that you’re a peaceful person, but some realities cannot be ignored.

Its not the solution, but it is a tragic necessity when confronted with unwarranted invasion. Especially of the barbaric kind Russia is perpetuating.
