Since long before Russia’s full-scale invasion of Ukraine in 2022, Moscow has spread disinformation to justify its aggression, disguising their longstanding premises that Ukraine is, allegedly, not a sovereign nation, and its statehood is conditioned upon an alliance with Russia. Countering these narratives is not only valuable for Ukrainians, but also for buoying any democratic transformations in Russia and for establishing a more nuanced understanding of the history of Central and Eastern Europe.
