Russian President Vladimir Putin and the Russian military command likely view maintaining the theater-wide initiative as a strategic imperative to win a war of attrition against Ukraine, and both the Ukrainian incursion in Kursk region and the Russian offensive effort in eastern Ukraine will impact whether Russian forces can retain the initiative in the short-term.
Russian forces seized the theater-wide initiative in November 2023 and have since conducted consistent offensive operations throughout eastern and northeastern Ukraine as part of a campaign designed to stretch Ukrainian forces and prevent Ukraine from accumulating the resources necessary to contest the initiative.
The Russian military has not pursued a new large-scale offensive operation in recent months in order to maintain a consistent offensive tempo in Ukraine, particularly in Donetsk region, and Putin and the Russian military command have accepted that months of fighting will continue to result in marginal tactical gains.
Putin has expressed a theory of victory in Ukraine that posits that Russian forces will be able to continue these gradual creeping advances indefinitely, however, while preventing Ukraine from conducting successful operationally significant counteroffensive operations.
Putin likely assesses that as long as Russia can retain the initiative and prevent Ukraine from conducting operationally significant counteroffensive operations, Russia can inflict decisive losses on Ukraine over the long-term while outlasting Western security assistance to Ukraine and Ukrainian efforts to mobilize more of Ukraine's economy and population for the war effort.
The Ukrainian incursion into Kursk region has temporarily allowed Ukrainian forces to seize the battlefield initiative on one sector of the frontline and begin contesting Russia's theater-wide initiative.
The Russian military appears to be attempting to maintain its offensive pressure in Donetsk region, especially its offensive operation to seize Pokrovsk, and likely hopes that sustained offensive tempo in Donetsk region will draw enough Ukrainian resources to defensive operations in the area to prevent Ukraine from contesting the battlefield initiative elsewhere by exploiting the theater-wide impacts of the incursion into Kursk region.
Just because Russian forces are prioritizing the offensive operation on Pokrovsk does not mean that Ukraine must decide to prioritize the defense of Pokrovsk over efforts elsewhere, however.
