Estimated Destructive Force
Progress in Disarmament
- Belarus transferred all of its Soviet-era tactical warheads to the Russian Federation by May 1993, while the transfer of strategic warheads was completed by November 1996. 
- On 1 December 2010, Belarus announced its plan to eliminate the country's remaining stocks of highly enriched uranium (HEU) – reported as approximately 230kg at the time – with U.S. help before the 2012 Nuclear Security Summit in Seoul, South Korea.  In October and November 2010, 88.7kg of HEU, including 46.7kg of fresh HEU fuel, were removed from several facilities.  However, Belarus suspended this agreement after the U.S. announced sanctions against Belarus in 2011.  Approximately 100 kilograms of HEU remain while talks on renewing the agreement are at an impasse.
