According to a Northeastern Expert, the balance of forces in the battle theater in Ukraine has not yet been determined.
According to experts in the region, the successful Ukrainian counterattack in the country’s northeast may have exposed Russian military weaknesses and dealt a blow to the Kremlin’s propaganda apparatus, but it does not yet imply that Ukraine has a sizable advantage over Russia to win the war outright. According to Pablo Calderon Martinez, an assistant professor of politics and international relations at Northeastern University – London, “There is no denial now that the [Russian] invasion of Ukraine failed,” He claims that the so-called “special operation,” as Russia likes to refer to their invasion of Ukraine, was meant to be swift and almost “surgical,” but instead it devolved into a battle of attrition.
