The battle in the Donbas has settled into an artillery duel where the Russians assault deeply entrenched Ukrainian positions. It's almost like WWI, so I'm sure casualties are very high on both sides, but since the Ukrainians are defending, probably significantly higher for the Russians. Meanwhile, because it began mobilizing when the war started, Ukraine now has 1 million men under arms.
If the Russians had any brains, they'd propose a settlement where they retreat to the Feb. 23rd lines, and ask for recognition of the Crimea annexation and annexing the parts of Donbas they already occupied and call that victory.
