Your source, Dennys, is a traitor and a deserter. He deserted his country when his country needed him most. I'm pretty sure that he is an able male of military age. He is lucky he got to escape. Unlike the remaining Ukrainian men, whose rights and freedoms are being trampled on by Zelenskiy's regime.
Dennys has a history of spreading fake, unconfirmed reports and fabricated narratives. But I do understand why certain people cling to his channel. Dennys helps perpetuate that parallel reality. The one where Ukraine is winning.
Despite the unconfirmed propaganda reports, reliable pro-Ukrainian sources (such as Deepstatemaps that draws their maps based on confirmed reports) paint a different picture.
The picture on the left is from today. The one on the right is from 2 days ago. Yes, the Ukrainian counter-offensive in Sumy is going very well. Let's forget about the fact that the Ukrainian army was smashed to bits in Kursk region and lost their 1300 square km. foothold there, failing to meet any of their objectives once again (capturing the Kursk NPP, using captured Kursk territory as a bargaining chip etc.).
You need to adjust your way of thinking. You don't know what Putin thinks or feels. And the reality on the ground is obvious to anyone that's been following this conflict from the beginning. Ukraine is losing. Losing men, losing territories. To a donkey-riding army that according to you hasn't even tried hitting any military targets.
But please do not let the facts and the solid logic get in the way of your commenting. I'm sure most of us enjoy reading through your regular updates from that parallel reality.
