| Ukraine really doesn't want war, the odds are stacked against them and without significant outside ground troops they'll be devastated even if Russia is as incompetent as they currently appear. Killing aggressors is often used as an excuse for the aggressors to be more aggressive and Russia's army is large enough to replace that convoy a few times over without much of a sweat. Violence also helps back the idea that Russia needs to be there to stop the violent nazis that state media has painted Ukrainians to be (goes without saying, this is completely fabricated). It's also a morale killer; a lot of Russians have Ukrainian relatives. A lot of the captured combatants are very young and seem confused about why they're there (yes, could just be propaganda). Ukraine just wants them to go home. The Ukrainian people don't really have a conflict with the Russian people. |
It definitely isn't "completely fabricated":

The real problem is, who gives a shit if a small unit in the Ukrainian National Guard is made up of far right extremists? It's a purely internal matter for the Ukrainians to deal with however they see fit, and provides zero justification for Russia's invasion.
But by lying and claiming it's a lie you're going to make anyone who looks into the truth behind the matter more likely to become sympathetic to the Russian version of events.
