Ukraine's Nuclear Disarmament and Its Aftermath
After the Soviet Union broke up, Ukraine had many nuclear weapons.
However, they couldn't control or maintain them, and other countries wanted them gone.
Ukraine decided to give them up to Russia in 1994, and in return, it was promised safety and respect from several countries.
Ukraine transferred its nuclear weapons and in return, the US, Russia and UK assured that its sovereignty will be respected.
Years later, Russia invaded Ukraine, breaking the promise they had made.
Ukraine inherited a vast nuclear arsenal after the USSR's fall in 1991.
Ukraine lacked control, maintenance capabilities, and faced international pressure to disarm.
The Budapest Memorandum of 1994 led to Ukraine giving up its nuclear weapons to Russia.
Ukraine received security assurances from Russia, the US, and the UK in exchange.
Russia's 2014 annexation of Crimea and 2022 invasion violated the Budapest Memorandum.
