- Abstract:
- Tensions with Iran are once again increasing. The slow implosion of the nuclear accord, Iran’s harassment of cargo ships, and the downing of a U.S. unmanned aircraft have made plain the risk of conflict between Iran and the United States. The dispute should also draw attention to the questionable preparedness of the United States and its allies to fight a war with Iran on short notice and deal with that war’s blowback across the Middle East and Europe. Regional missile defense architectures are an important part of that preparedness. Iran has the largest and most diverse supply of ballistic missiles in the Middle East region, and Tehran has shown an ability and willingness to use them in combat operations.1 Iran is also learning to employ other kinds of aerial threats, such as long-range cruise missiles and unmanned aerial vehicles (UAVs). In a conflict with Iran, U.S. and allied forces would likely face a wide spectrum of air and missile threats. The biggest U.S. investment in Iran-centric missile defenses has been the European Phased Adaptive Approach (EPAA). EPAA is a phased buildup of U.S. missile defense assets in and around Europe to deter and, if necessary, limit damage from an Iranian missile attack on the North Atlantic Treaty Organization (NATO). Yet the EPAA architecture is heavily dependent on the nominal, unencumbered performance of a single radar deployed relatively close to Iran. This produces a single point of failure susceptible to malfunction or operator error. It also presents an Achilles’ heel that a determined or imaginative adversary could exploit. Iran certainly fits both descriptors. In 1958, strategist Albert Wohlstetter wrote that U.S. confidence in its nuclear second-strike ability was achieved only by “ignoring the full range of sensible enemy plans.”2 This same critical judgment should be applied to confidence in the EPAA as currently configured. Inasmuch as a sensible adversary such as Iran relies upon its missile forces to achieve its defense goals, it should be credited with the foresight to target single points of failure that would preclude the effective application of that missile force. Fortunately, there are practical steps that NATO and the United States can take to further adapt EPAA for greater resiliency. Upgrades to existing radars, the integration of allied radars into the missile defense mission, and the addition of air and space-based sensors would do much to improve EPAA’s capability and survivability, improving U.S. and NATO preparedness for an unexpected Middle East conflict.
