Most Russian speakers in the Donbas don’t want anything to do with Moscow rule. That is why the Ukrainians gain much more from human intel and not just drone observation.
The Ukrainian military is much more efficient and capable than the Russian army. Ukraine’s deep precision strikes are destroying the Russian economy. Locally, the Russian summer offensive is a colossal failure that cost a shocking amount of casualties and netted the invaders no new lands.
The Ukrainian Cossacks have always been tough customers.
Ukraine is doomed.
