Threat Assessment Briefs are provided as part of the "Realistic Threat Assessments and Responses Project" led by ACA Senior Fellow Greg Thielmann. Each brief takes an objective look at key security threats, and considers policy responses to those threats.
Strategic Missile Defense offers no real disincentive for rogue regimes such as North Korea or Iran to develop or use ballistic missiles, nor does it offer any protection against the more acute threat of terrorist groups smuggling weapons of mass destruction into the United States. Instead the aggressive pursuit of strategic missile defense makes it more difficult to constrain the potential offensive nuclear threat from Russia and China.
Iran’s pursuit of nuclear technology, and possibly nuclear weapons, stems from its complicated threat environment and the historical grievances it harbors concerning the United States. Tehran now faces large numbers of U.S. troops in its neighbors to the west and east with few regional allies. The most productive path for averting nuclear weapons development in Iran is for Washington to seek to alter Iran’s threat perceptions.
