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.
