Summary of "Analyzing the Impact of Preventive Strikes Against Iran's Nuclear Facilities"

Core Content

This report, authored by Anthony H. Cordesman and Abdullah Toukan for the Center for Strategic & International Studies (CSIS), examines the potential for the United States to lead a preventive military strike against Iran's nuclear facilities and ballistic missile bases if diplomatic and peaceful options fail. It also explores the U.S. and Gulf Cooperation Council (GCC) defense strategies against possible Iranian retaliation, particularly through ballistic missile attacks on regional allies.

Main Objectives of a Military Strike

• To halt or significantly delay Iran's nuclear program.
• To set it back by at least five years or one year.
• To destroy or damage key nuclear and missile facilities, including:
  • Nuclear enrichment and research facilities.
  • Ballistic missile bases.
  • Missile production facilities.
  • Mobile missile launchers.
• The goal is to reduce Iran's retaliatory capability and prevent it from acquiring nuclear weapons.

U.S. Capability and Strategy

• The U.S. is the only country capable of carrying out a successful preventive strike due to its advanced airpower, intelligence, and command and control capabilities.
• The U.S. would need to deploy a large force, including:
  • B-2 bombers.
  • Fighter escorts (F-18s, F-15Es, F-16Cs).
  • Electronic warfare aircraft.
  • Air-to-air refueling support.
• The mission would involve multiple phases and would require near real-time intelligence to target mobile and underground facilities effectively.
• The U.S. is also building a Multi-Tier Ballistic Missile Defense (BMD) System in the Gulf, including:
  • THAAD and PAC-3 missile systems.
  • Aegis-equipped warships.
  • An integrated early warning radar system across GCC states.

Iranian Capabilities and Threats

• Iran's military strategy includes deterrence, asymmetrical retaliation, and attrition warfare.
• Iran's conventional military is growing, with expanded naval operations and improved capabilities in the Gulf of Oman, Persian Gulf, and Caspian Sea.
• Iran's ballistic missile force is a major threat, especially to the GCC states, which could suffer significant damage from a retaliatory strike.
• Iran has a network of mobile missile launchers and continues to develop longer-range missiles, including a 2,000-km medium-range ballistic missile, the Ashura.
• Iran is also involved in supporting militant groups like Hezbollah and Hamas, which could be used for retaliation.

Key Considerations

• The U.S. is working with GCC allies to enhance ballistic missile defense and freedom of navigation in the Strait of Hormuz, which is vital for energy exports.
• Israel lacks the capability to carry out a preventive strike that would significantly delay Iran's nuclear program for more than a few years.
• A preventive strike by the U.S. could have destabilizing effects in the Middle East, potentially leading to a nuclear weapons race.
• The U.S. must consider the law of unintended consequences, as such strikes could provoke a broader regional conflict.

Military Strike Force Allocation

• Main Nuclear Facilities: 5 targets, 2 aircraft per target → 10 B-2 bombers.
• Missile Bases: 8 targets, 2 aircraft per base → 16 strike aircraft.
• Missile Production Facilities: 15 targets, 2 aircraft per target → 30 strike aircraft.
• Mobile Missile Launchers: 22 assumed launchers, 2 aircraft per launcher → 44 strike aircraft.
• Total: 10 B-2 bombers + 90 strike aircraft = 100 aircraft.

Counterair Missions

• Offensive Counterair (OCA) missions are essential for:
  • Destroying Iranian air defense systems.
  • Ensuring the survival of U.S. and allied aircraft.
  • Supporting the strike with suppression of enemy air defense (SEAD), fighter sweeps, and escort operations.
• The effectiveness of OCA operations depends on:
  • Advanced weapons accuracy.
  • Improved survivability of aircraft.
  • Larger payloads and intelligence support.

Conclusion

The report underscores the U.S. as the sole viable actor in a preventive strike against Iran's nuclear and missile infrastructure due to its overwhelming military superiority. However, it also highlights the need for diplomatic efforts and strategic partnerships with GCC allies to avoid unintended consequences and to ensure a sustainable defense posture in the region. The potential for regional instability and global economic impact is a critical concern, especially given the significance of the Strait of Hormuz for global oil supplies.
