Russian media analysis believe that Ukraine's polity is now resigned to the fact that they can't really militarily defeat Russia alone. And so they've shifted their strategy to use Ukrainian military to create high impact media headlines, to please their western "financiers" and to psychologically demoralise the Russians. That does make sense as attacks like this while being demoralising doesn't really offer any real military breakthrough to the Ukrainians, nor is it likely to stop the Russian advances.
The Russians already occupy around 20% of Ukrainian territory which the Ukrainians have been unable to take back. Since last year, the Russians have reportedly captured nearly 2000+ kms more of territory from the Ukrainian forces (including the Russian regions that were under Ukrainian control). And the Ukrainians forces can't realistically launch another major counter-offensive as they are very wary of running out of manpower (Ukrainians have 1/4th the wartime population of the Russians, and thus can't replenish their military as much as the Russians can).
Thus, it is an undeniable fact that right now, the Russian military have the advantage and the Ukrainian military is losing the war.
What remains to be seen is how much longer is the Zelensky administration willing to gamble that Russian economy will soon collapse or Putin may be deposed or NATO or EU boots will soon join the Ukranian forces to fight the Russians?
