On October 7, 2009, Senior Fellow Greg Thielmann participated in a briefing to congressional staffers and the press on the Iranian nuclear program arranged by Congressman Ron Paul (R-TX). His remarks at the Cannon House Office Building built on his September ACA Threat Assessment Brief, "Is There Time to Prevent an Iranian Nuclear Weapon?" (PDF). Watch it here.
The Obama administration has identified September as a time for reassessing its approach to negotiation with Tehran over Iran's nuclear program. It is imperative that this reassessment be based on a realistic appraisal of Iran's weaponization capabilities and limitations and not fall prey to politically motivated hyperbole. Iran's nuclear program is undeniably bringing that country closer to an ability to construct nuclear weapons-bad news for the region, the United States, and the world. Yet, a nuclear-armed Iran is years, not months, away, which is ample time for negotiating an outcome that prevents Iran from becoming a nuclear-weapon state while strengthening the nuclear Nonproliferation Treaty.
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.
