Senators Nunn and Lugar sponsored the initiative that became Title 22 (chapter 68a) of U.S. Code and authorized the Cooperative Threat Reduction program (also called the Nunn-Lugar Program). Now part of the Defense Threat Reduction Agency, the agency describes the program's goal "to "prevent the proliferation of weapons of mass destruction (WMD) and related materials, technologies and expertise from former Soviet Union (FSU) states. This includes providing for the safe destruction of Soviet era WMD, associated delivery systems and related infrastructure, and consolidating and securing FSU WMD and related technology and materials."
The program was "originally sponsored...as an amendment to the Conventional Armed Forces in Europe Treaty Implementation Act."
"Congress established the CTR Program in December 1991 as the "Soviet Nuclear Threat Reduction Act." It was later renamed the "Cooperative Threat Reduction Program" in 1993 legislation, and has received over $5.9 billion through annual defense appropriations since 1991. Assistance has been provided to the former Soviet republics (primarily Russia, Ukraine, Kazakhstan, Georgia, Uzbekistan, and Azerbaijan)."
