The fundamental aim of Golden Dome is to protect the United States from air or space-based missiles armed with a variety of warheads: nuclear, chemical, biological, or conventional. Golden Dome will be made available to key allies should they deem it necessary for their own defenses in an increasingly complex global security environment. However, the level of interest these allies have in negotiating the terms of missile defenses from the U.S. remains to be seen.

While moving beyond the technical development of SDI, Golden Dome is not ushering a new age of missile defense strategy. A national missile defense policy has been in place since the 1990s following a hotly debated period in Congress where a “placebo defense” was finally deployed. The term “placebo defense” was coined by prolific political strategist Dr. William Van Cleave, who advocated for a layered concept of missile defense while he was a member of “Team B.” Team B was commissioned by the-then Director of Central Intelligence, President George H.W. Bush for the purpose of providing the government with alternative intelligence assessments and policy guidance regarding the Soviet strategic threat.

Dr. Van Cleave first used the term “placebo defense” in lectures at the Department of Defense & Strategic Studies at Missouri State University in 1996. While not officially defined in any academic paper, “placebo defense” describes the U.S. policy of deploying limited missile defenses incapable of defending against significant ballistic missile attack from either Russia or China. Rather, such limited missile defenses instead minimize the threat by rogue states like North Korea and Iran. The goal in part was to silence the critics who claim the U.S. must at least be able to defend itself from those rogue nations more likely to launch one or two missiles at U.S. forces overseas, or key coastal areas of the country.

The Team B concept of layered missile defense was supported by former SDI officials who advocated for a space-based laser (SBL) system to provide the most effective method of intercepting ballistic missiles. While this would be ideal for balancing technical feasibility and overall program cost, SBLs were not supported by Congress and follow-on administrations. Valuable research and development have since been neglected, making SBLs unlikely achievable anytime soon.

Golden Dome is now poised to move forward with some of the Team B concepts and additional strategists since the 1990s. To move Golden Dome forward rapidly, it is time to reconsider Brilliant Pebbles, which is also referred to as Future Space-Based Interceptors. Designed by Lawerence Livermore National Laboratory, Brilliant Pebbles envisioned placing small space-based interceptors (weighing around 10 kilograms) in Low Earth Orbit (LEO) capable of colliding with intercontinental ballistic missiles during the boost-phase of their trajectory. These interceptors would remain in orbit for only 18 months. Brilliant Pebbles was cancelled in 1993 due to a lack of political support in Congress despite some strategists arguing the technical feasibility of the program and its technical readiness for deployment in the near term.

Since the program’s end, the technical efficiency of small pump-fed engines and the impulse of solid axial engines, the areas of technological development that limited the concept in the late 1980s, have improved. It is now possible for an interceptor to reach 20g acceleration and cover a range of 800 km, well beyond the capabilities in the original project. Further mission analysis is still needed to determine the number of Brilliant Pebbles required to provide adequate missile defenses within the Golden Dome strategy. Furthermore, the cost to deploy Brilliant Pebbles using this concept will also be vastly reduced using current U.S. space launch capabilities provides by companies such as SpaceX and Blue Origin.

The ability of Golden Dome to effectively protect the U.S. from air and space missile threats fundamentally relies on selecting the most effective space-based missile defense system. Brilliant Pebbles is a system whose maturity can be advanced quickly and cost effectively to provide a boost-phase intercept capability. This could finally put to an end to the “placebo” missile defense system which leaves the U.S. insufficiently defended.

Why You Need This Report

The ICBM EAR (Emerging Affairs Report) for the Week of March 3, 2025, prepared by Peter Huessy, President of Geo-Strategic Analysis and Senior Fellow at the National Institute for Deterrence Studies, offers an authoritative, real-time assessment of critical defense and strategic developments impacting U.S. national security. This report consolidates essential intelligence and policy analysis on ICBM modernization, homeland missile defense, congressional budget battles, strategic threats from China, Russia, and Iran, and broader global deterrence dynamics.

As global threats intensify, policymakers, defense professionals, and industry leaders need a consolidated, insightful briefing to navigate the shifting landscape of great power competition and nuclear deterrence strategy. This report delivers precisely that—essential updates, expert commentary, and strategic foresight that decision-makers cannot afford to overlook.

Key Themes & Strategic Insights

1. Critical Developments in Homeland Missile Defense & Nuclear Deterrence

• The “Golden Dome” missile defense initiative, backed by congressional leaders and STRATCOM, underscores a growing commitment to protecting the U.S. homeland from emerging missile threats.
• General Alvin, USAF Chief of Staff, affirms the Air Force’s pivotal role in nuclear deterrence and missile defense, reinforcing its responsibility for two-thirds of the nuclear triad and three-fourths of nuclear command, control, and communications (NC3).
• Upcoming ICBM infrastructure modernization at Vandenberg Space Force Base highlights the urgency of maintaining a credible nuclear deterrent against adversarial advancements.

2. Congressional & Budgetary Realities Impacting National Defense

• As the FY25 budget debate intensifies, the threat of a yearlong Continuing Resolution (CR) poses risks to defense funding, potentially leaving the U.S. military underfunded by $8 billion below proposed levels.
• Misinformation regarding an “8% defense cut” is addressed—while no drastic cuts are proposed, funding reallocations emphasize priority programs like Sentinel ICBM modernization and Columbia-class submarines.
• With a $2 trillion annual deficit, balancing national security needs with fiscal realities remains a critical challenge.

3. Growing Threats from China, Russia, and Iran

• China’s defense budget expands by 7.2%, accelerating military modernization, expanding nuclear capabilities, and strengthening island chain defenses in the Pacific.
• Russia’s Arctic militarization, border buildups, and nuclear brinkmanship highlight its continued push for strategic dominance.
• Iran’s sevenfold increase in highly enriched uranium (HEU) production, coupled with escalating proxy conflicts, presents a growing nuclear proliferation threat.
• European defense spending surge ($860 billion over four years) signals a shift in NATO’s strategic posture amidst rising concerns over Russia’s long-term objectives.
