The assessment is absolute BS. Ukies are getting a royal beatdown in the north of Kherson region, and are currently evacuating Nikolayev.
I can’t exclude that the Russian forces are going to leave Kherson, but that if it is going to be unreasonable to hold to it, like if the Ukies are to finally blow the dam.
Given the news blackout from both sides, what is the source of your information?
The Ukrainians are evacuating Mykolaiv? What source reported that? Are you sure that they aren’t also evacuating Kyiv? 🙄
