>You can barely tell the difference between a territorial control map from 2023 and 2026
Last time I was paying close attention (maybe 8 months ago) the fighting was heavy in Pokrovsk, Myrnohrad, and not yet in Konstantynivka. Now all three of those are well within Russian control. And that seems to be the story all over the front. There may be some temporary regressions, and occasional slow downs, but overall the Russian side is continually pushing.

They're not moving quickly. That's the way they're choosing to fight the war, and also due to the strength and resilience of the Ukrainian side, along with roughly 300 billion Euros pumped into the war by NATO so far. I don't think the slow methodical approach is evidence of weakness. Taking the average territory capture rate since 2022, the entire Donbas would be under Russian control mid next year. Using only the relatively slow 2026 rates, the entire Donbas would still be under Russian control in less than 5 more years.
