LOL, remind me who retreated from the annexed regional capital Kherson?
On 9 November, Russian general Sergey Surovikin announced the withdrawal of troops from Kherson and the west bank of the Dnieper. He claimed that the reasoning for this decision was that Kherson and nearby settlements were not able to be properly supplied and that civilians were in danger from Ukrainian shelling.
You're nuts. The Russian objective, apart from liberating Donesk and Lugansk and building a land bridge from Crimea to mainland Russia, is to destroy the Ukraine military. You're blind or stupid to grasp that. And, that's what they are doing.
