In his interview with NPR, Professor Sergey Radchenko discusses Russia's impending update to its nuclear doctrine. He explains that this shift reflects the Kremlin's intent to signal greater readiness to use nuclear weapons under certain circumstances, particularly in response to perceived existential threats. Radchenko notes that while the move is partly aimed at deterring the West, it also reflects Russia's growing isolation and the potential for miscalculation in an increasingly tense global environment.
