Policy white papers are objective assessments of key security and disarmament issues with recommended policy responses by Arms Control Association staff and fellows.
The nearly 2,000 nuclear warheads on Russian ICBMs and submarine-launched ballistic missiles constitute the sole near-term existential threat to the United States. The U.S. response to this threat has been to maintain the nuclear war-fighting posture adopted during the Cold War. Yet, this posture does not lead toward an improvement in U.S. security; it merely reinforces Russia’s incentive to persist in its own anachronistic security calculus. The New START and a transformational post-Cold War Nuclear Posture Review would clear the path for major U.S. and Russian arms reductions, laying the foundation for a rejuvenated effort to halt nuclear nonproliferation and for engaging other nuclear-weapon states in arms control.
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.
Although the possibility of Iranian nuclear weapons is a major concern for Israel and the United States, leaving the "military option" on the table is counterproductive. Preventive military action by either country against Iran's nuclear facilities would only delay, rather than halt, Tehran's nuclear program, and it would cause Iran to retaliate against the United States as well as Israel. The aftermath of such an attack would be disastrous for the U.S.position in the region-particularly for relations with Israel and with Iraq-and its position in the wider world.
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.
