From The New York Times:
WASHINGTON — When Russia shifted its military campaign to focus on eastern Ukraine this spring, senior officials in the Biden administration said the next four to six weeks of fighting would determine the war’s eventual path.
That time has passed, and officials say the picture is increasingly clear: Russia is likely to end up with more territory, they said, but neither side will gain full control of the region as a depleted Russian military faces an opponent armed with increasingly sophisticated weapons.
