Even before the first atomic weapons test in 1945, a number of nations have tried adding weapons of mass destruction (WMDs) to their arsenals. Many succeeded. But as time passed and social and political realities changed, some of these nations realized the potential destructive threat posed by these weapons.

As part of the United States’ efforts to reduce the threat of WMDs, DTRA has cultivated partnerships with a number of countries to help them address these threats. Through programs including the Nunn-Lugar Cooperative Threat Reduction Program, the International Counterproliferation Program, the Global Initiative to Combat Nuclear Terrorism, the Small Arms and Light Weapons assistance program and many others, DTRA works with others not only to counter the threat posed by WMD, but to reduce it.

Our international partners include the United Kingdom, Canada, France, Germany, Norway, Czech Republic, Russia, Armenia, Azerbaijan, Georgia, Kazakhstan, Ukraine, Uzbekistan, Israel, India, Republic of Korea, Japan, Singapore, Australia and New Zealand. We also work with a number of international organizations including the International Atomic Energy Agency (IAEA) and the Organization for the Prohibition of Chemical Weapons (OPCW).
