Kharkiv war to exhaustion. Russia will break Ukraine's defense?

The Russian offensive in the Kharkiv Oblast was loud in May this year, erstwhile Russian units crossed the border with Ukraine and the barrels of their tanks were aimed at Kharkiv and Volchansk. This operation ended in failure, and the Russians did not approach Kharkov's prefield and were stuck in Volchansk. Meanwhile, the situation in the east part of the Kharkiv region on the Oskoł River is developing worryingly for Ukrainians. The reason for this is the exhaustion of war and the request to shift troops to another sections of the front line.
