Ukraine Flag for Ukraine

Country Spotlight

Upon Ukraine’s 1991 independence, over 1,700 Soviet nuclear weapons were left on its territory. Ukraine never possessed operational control of the weapons, and all were removed to Russia under a 1994 agreement in exchange for security assurances. Ukraine has accused Russia of violating the agreement with its 2014 annexation of Crimea, and again with the 2022 Russian invasion of Ukraine.
