Ukraine's Unprecedented Invasion of Russian Territory

Ukrainian forces achieved a significant milestone by crossing into Russian territory, a bold maneuver that took the Russian military by surprise. This unprecedented act allowed Ukraine to claim approximately a thousand square kilometers within Kursk Oblast, a region previously considered secure from foreign invasion, especially by a nuclear-armed nation. The successful incursion calls into question the reliability of Russia's nuclear deterrent, as it appears to challenge President Putin's promises of retaliatory strikes against any infringement on Russian sovereignty. By invading Russian sovereign territory without provoking a nuclear response, Ukraine has effectively undermined the traditional narrative of invulnerability associated with nuclear powers.
