Could the Ukrainian incursion in Kursk become a turning point in the war?

The Russians and the Ukrainians seem to be fighting in two parallel dimensions: both contending armies claim military success in two different regions.

While the Ukrainian incursion in the western Russian territory of Kursk seems to be steadily gaining ground, the Russians are close to achieving a goal of their own in the Donbas after they took the town of Niu-York and advance on a key transport junction of Pokrovsk.

In the Kursk area, the Ukrainian forces are trying to seize Korenovo. The fall of this city would allow them to strengthen their defences in Russian territory and build a coherent "buffer zone" to protect Kharkiv and other northern cities.

Such a buffer zone, stated by President Volodymyr Zelenskyy to be the incursion's main goal, would be a major operational success for the Ukrainians.
