President Vladimir Putin vowed that Ukraine's incursion into the Kursk region will not halt Russia's military advances in eastern Ukraine, branding the Ukrainian forces as 'bandits.' The situation marks a significant moment in warfare, as Ukraine's control of territory in Kursk challenges long-held assumptions about nuclear deterrence involving nuclear powers. Despite initial gains, critics in Kyiv express concerns that the Ukrainian military's focus on Kursk has left critical areas like Pokrovsk vulnerable to Russian counteroffensives. Although Ukrainian forces have slowed their advance after 25 days, they continue to push towards Glushkovo, a key location for Russian defenses. Additionally, Russian rebels have expressed frustration at being excluded from Ukraine's operations in Kursk, indicating political rivalries within Ukrainian military leadership. The evolving dynamics of the conflict are prompting global reevaluation of nuclear strategies and military tactics.
