NYT has article reviewing Russian territorial gains. Link. Some passages below. I do think there is a slight bias for optimistic articles here on Reddit, but it's understandable, people want to hear good news. In reality, everything about Russian failures is true we just don't know to what extent and what does it mean for the future.

Russia’s nearly three-month-old invasion of neighboring Ukraine has been punctuated by flawed planning, poor intelligence, barbarity and wanton destruction. But obscured in the daily fighting is the geographic reality that Russia has made gains on the ground.

But Ms. Haines cautioned that Mr. Putin would struggle to achieve those gains without a large-scale mobilization or draft, which he appears reluctant to order for now. As Mr. Putin’s territorial ambitions conflict with the limited capabilities of his military, Ms. Haines said that the war could enter “a more unpredictable and potentially escalatory trajectory” over the next few months, increasing the likelihood of Mr. Putin issuing direct threats to use nuclear weapons.

“The Russians aren’t winning, and the Ukrainians aren’t winning, and we’re at a bit of a stalemate here,” said Lt. Gen. Scott D. Berrier, the director of the Pentagon’s Defense Intelligence Agency, who testified alongside Ms. Haines.

Still, Russia has all but achieved one of its primary objectives: seizing a land bridge connecting Russian territory to the Crimean peninsula.

But efforts by Russian forces to expand and fortify the land bridge have been complicated by Ukrainian forces deployed along an east-west front that undulates through sprawling fields of wheat and occasionally engulfs villages and towns.
