Belarus
Country Spotlight
Belarus gained independence following the 1991 collapse of the Soviet Union and inherited a nuclear weapons infrastructure. It transferred all remaining nuclear weapons to Russia by 1996. Today, Belarus is a close ally of Russia and participated in Russia’s 2022 invasion of Ukraine. In February 2022, Ukraine amended its constitution to allow Russia to deploy nuclear weapons on Belarussian territory.
