What is the Cooperative Threat Reduction program?
The Cooperative Threat Reduction (CTR) program, also known as the Nunn-Lugar Act, was initiated by U.S. Senators Sam Nunn and Richard Lugar in 1991. It aimed to help Russia and other former Soviet states dismantle and dispose of their nuclear weapons.
After the Soviet Union collapsed in December 1991, its nuclear arsenal was spread across Russia, Belarus, Ukraine, and Kazakhstan, raising concerns about the weapons' security. The U.S. provided funding to eliminate and store nuclear material, improve communication between the American and Russian militaries, convert Russian defense industries, ensure environmental safety at former nuclear sites, and provide employment for former Russian nuclear scientists.
Between 1992 and 1997, all nuclear materials were safely moved to Russia. The U.S. oversaw the dismantling of a significant portion of the Soviet nuclear arsenal and confirmed that the leftover material had been safely stored or disposed of.

Why did the United States create the Cooperative Threat Reduction program?
The United States created the Cooperative Threat Reduction (CTR) program, also known as the Nunn-Lugar Act, to assist Russia and other former Soviet states in dismantling and disposing of their nuclear weapons during the 1990s. The program was prompted by the collapse of the Soviet Union in December 1991, which raised concerns about the control and security of the vast Soviet nuclear arsenal, chemical weapons, and biological-weapons programs, which were now spread across multiple newly independent countries. The CTR program was later expanded to include safeguarding, securing, and deactivating weapons of mass destruction outside the former Soviet Union to prevent the trafficking of WMDs and related technologies.

What kinds of threats does this program try to reduce?
The Cooperative Threat Reduction (CTR) program, also known as the Nunn-Lugar Act, was initiated to help Russia and other former Soviet states dismantle and dispose of their nuclear weapons in the 1990s.
The CTR program addresses critical concerns about the security of weapons in newly formed governments after the Soviet Union collapsed. It aimed to prevent the proliferation of weapons of mass destruction (WMDs) and related technologies by safeguarding and deactivating WMDs both within the former Soviet Union and elsewhere. The program has since expanded to include improving communication between the U.S. and Russian militaries, converting Russian defense industries, ensuring environmental safety at former nuclear sites, and providing employment for former Russian nuclear scientists.

How does the program help reduce the risk of nuclear weapons spreading?
The Cooperative Threat Reduction (CTR) program, also known as the Nunn-Lugar Act, was initiated by U.S. Senators Sam Nunn and Richard Lugar to help Russia and other former Soviet countries dismantle and dispose of their nuclear weapons.
After the Soviet Union collapsed in 1991, its nuclear arsenal was spread across four newly independent countries: Russia, Belarus, Ukraine, and Kazakhstan. The CTR program was designed to secure these weapons, addressing concerns about their safety and control.
Through U.S. funding, the CTR program facilitated the transfer of nuclear arsenals from Belarus, Kazakhstan, and Ukraine to Russia by 1994. The program also improved communication between the American and Russian militaries and converted Russian defense industries into peaceful civilian industries. The Defense Threat Reduction Agency (DTRA) was later established to oversee and implement the CTR program. Overall, the Nunn-Lugar Act contributed to the peaceful resolution of the Cold War and prevented the spread of Soviet nuclear and chemical weapons.

Which countries have partnered with the United States in this program?
The Cooperative Threat Reduction (CTR) program, also known as the Nunn-Lugar Act, was initiated by U.S. Senators Sam Nunn and Richard Lugar to help Russia and other former Soviet countries dismantle and dispose of their nuclear weapons.
Initially, the CTR program focused on aiding Belarus, Kazakhstan, and Ukraine in transferring their nuclear arsenals to Russia. By 1994, with U.S. assistance, these countries had successfully moved all nuclear weapons to Russia.
After the initial success, the program's focus shifted primarily to Russia. The United States offered funding to improve communication between the American and Russian militaries, convert Russian defense industries into peaceful civilian industries, ensure the environmental safety of former nuclear sites, and provide new employment for former Russian nuclear scientists and other military personnel.

Cooperative Threat Reduction (CTR), plan developed by U.S. Senators Sam Nunn (Democrat, Georgia) and Richard Lugar (Republican, Indiana) to assist Russia and other former Soviet states in dismantling and disposing of their nuclear weapons during the 1990s.
In August 1991 a military coup nearly overthrew Soviet leader Mikhail Gorbachev. That event brought into focus the possibility that the Soviet Union’s vast nuclear arsenal could fall under the control of an unstable military government. Greatly alarmed, U.S. government officials proposed working with the Soviets to secure their nuclear weapons. Before such an agreement could be accomplished, however, the Soviet Union collapsed, on December 25, 1991.
At that time the Soviet Union possessed approximately 30,000 nuclear missiles, 40,000 tons of chemical weapons, and a large biological-weapons program. When the Soviet Union broke apart, those weapons were spread among four newly independent countries: Russia, Belarus, Ukraine, and Kazakhstan. The situation raised two critical concerns. First, could those newly formed governments be trusted to harbour such dangerous weapons? Second, were those new countries capable of safeguarding the weapons?
To ease those concerns, in 1991 Nunn and Lugar cosponsored the National Defense Authorization Act. The act originally provided U.S. funding for either the elimination of Soviet nuclear weapons or their removal to carefully guarded sites, storage of nuclear material obtained from decommissioned missiles, and efforts to prevent the sale or illegal dispersal of destructive weapons. The act proposed that the United States spend roughly $400 million per year to achieve those goals.
By 1994 Belarus, Kazakhstan, and Ukraine—with the assistance of the United States—had transferred all of their nuclear arsenals to Russia, thereby eliminating fears about the security of weapons in those countries. The focus of U.S. efforts then turned primarily to Russia. In addition to eliminating and storing nuclear material, the United States provided funding to improve communications between the American and Russian militaries, to convert Russian defense industries into peaceful civilian industries, to ensure the environmental safety of former nuclear sites, and to provide new employment for former Russian nuclear scientists and other military personnel. The U.S. Departments of State, Defense, and Energy all worked to attain those objectives.
Overall, the Nunn-Lugar legislation was highly successful. Between 1992 and 1997, all nuclear materials were moved safely to Russia. U.S. officials oversaw the dismantling of a significant portion of the Soviet nuclear arsenal and subsequently confirmed that the leftover material from those weapons had been either safely stored or disposed of. Furthermore, relations between the former Cold War adversaries, the United States and Russia, were immensely improved.
Nevertheless, some members of Congress denounced the conversion of Russia’s defense industries into civilian industries and the use of funding to employ former employees of the Soviet defense establishment. That funding, they argued, constituted subsidies to the Russian economy and did not actually promote U.S. security. Distrust bred during the Cold War also lingered; some members of Congress feared that Russia was using the funding for military purposes, such as the war against separatist rebels in Chechnya.
Consequently, in 1997 the act was revised to cover only the three original principles formulated in 1991. Still, the Nunn-Lugar Act undeniably contributed to the peaceful resolution of the Cold War and the prevention of the unwanted spread of Soviet nuclear and chemical weapons.
