After the collapse of the Soviet Union, Ukraine found itself in possession of a substantial nuclear arsenal.

The current conflict between Russia and Ukraine underscores the challenges Ukraine faces in terms of security without the protection of nuclear deterrence. This situation has brought to light the vulnerability of Ukraine’s security landscape.
