Yes, Russians didn't manage to take Kiev or Kharkiv. But that doesn't change the fact that they are making progress in the east and the south. Wars have more than one front.
they've failed to achieve their major objectives and now are struggling with much smaller objectives. But evidence suggests they still want to conquer the whole country no matter how ridiculous.
Russia does not have what it takes to dissuade Ukraine from continuing to fight and they can't sustain the war effort as long, the longer the war goes the larger the Ukrainian military gets and the more hardware from the west it gets while Russia struggles with recruitment and military manufacturing under sanctions.
I know youtube videos from random people are rarely convincing but Perun has a really good one going step by step how Russia is unable to win this war just based on their difficulty with waging a long war.
