In February 2022, days after Russian forces crossed into Ukraine, Putin placed his nuclear arsenal on high alert and warned that any nation interfering would face consequences unlike any in its history. The warning to those who might intervene – specifically NATO. Four years on, NATO has provided extensive military and economic support to Ukraine without paying the price Putin had threatened. However, the threat still begs a question the U.S. has never answered. How would Washington protect the homeland, rather than merely avenge a nuclear strike? President Biden warned Moscow of severe consequences for any nuclear use in Ukraine but kept the American response ambiguous. The U.S. may or may not use nuclear weapons against Russia in defense of Ukraine, but a different reaction may occur if the target were a NATO country.  

Because of the distance between the two countries, a Russian strike on the U.S. would likely require long-range ballistic missiles launched from land or submarine. Even though eighty years of deterrence have kept that prospect remote, a single failure such as a misinterpretation or escalatory mobilization of forces could lead to a catastrophic reaction. The U.S. fields layered interceptors, yet the possibility of wide devastation remains. In January 2025, President Trump issued Executive Order 14186 which launched the “Golden Dome” initiative. The order, titled “The Iron Dome for America,” directed the Pentagon to develop a more sophisticated, layered shield against ballistic, hypersonic, and cruise missiles. The concept is analogous in purpose to Israel’s “Iron Dome,” but the planned U.S. architecture is far broader. It calls for space-based sensors, interceptors, and  non-kinetic capabilities. Potential systems could even include directed-energy weapons such as lasers.  

Antimissile defense is not new. In the 1980s, President Reagan initiated the Strategic Defense Initiative, more widely known as Star Wars. The program envisioned, among others, a space-based antimissile system that could provide a comprehensive defense against enemy missiles. That vision never came to fruition. However, technology has evolved, and the U.S. now operates Ground-Based Midcourse Defense, Aegis, THAAD and Patriot which are foundations for Golden Dome. These could build on and be consolidated to add new space-based antimissile capabilities. However, there are problems with this approach. The Government Accounting Office has documented challenges in transitioning DOD directed-energy prototypes, including high-energy lasers, into operational use and the Congressional Budget Office (CBO) assesses that directed-energy weapons, such as lasers, are unlikely to be fielded soon. Another problem is that the Golden Dome’s cost is still unknown. The CBO’s estimate is that a national missile defense architecture broadly consistent with the executive order could cost upwards of $1.2 trillion to develop, deploy, and operate over two decades. Every dollar carries an opportunity cost, reducing the: money that could be used to modernize other systems or reduce the national debt.  

Further, determining the Golden Dome’s effectiveness is problematic due to the difficulty of  intercepting ballistic missiles, and the need is to stop multiple missiles or further influence an adversary’s actions. The CBO found that a national missile defense architecture of this type could fully engage a regional-adversary attack or a small-scale attack by a peer adversary, but it could be overwhelmed by a full-scale attack from Russia or China.  

The CBO also warned that deployment could prompt adversaries to increase missile inventories, expand long-range arsenals, or pursue more effective countermeasures, including nuclear weapons. While the intention of the dome would be to make America safer, it could do the opposite. A commonly cited anecdote, known as the cobra effect, offers a warning about best-laid plans. This anecdote purports that British officials in colonial India offered a bounty for dead cobras; residents allegedly began breeding them for the reward, and when the bounty ended, the snakes were released which made the metropolitan areas in India more unsafe. A policy intended to reduce the cobra population produced the opposite result. The same could be true of the Golden Dome and must be considered in the calculus for its implementation.  

Concerns for Golden Dome go beyond the dome antimissile defense. A shield intended to reduce American vulnerability could make an adversary feel more exposed, encouraging it to build or diversify forces in other areas. Russia condemned Golden Dome arguing weapons in space are a provocation and they militarize space. The Soviets had a similar reaction to the Star Wars program. Russia may simply build more missiles and decoys to ensure enough survive. Russia is positioned to do so with impunity given that New START expired in February 2026. For the first time in decades the largest arsenals on earth are no longer bound by a bilateral cap.  

Whoever follows Putin may well prove worse. Even thought the forgoing text focusses on Russia, other adversaries are not far behind. North Korea continues to expand and diversify its nuclear and ballistic-missile capabilities. China continues a major expansion of its nuclear and missile forces. An even with the assassination of Supreme Leader Ali Khamenei, the Iranian regime continues to show an unwillingness to curb their pursuit of missiles and weapons of mass destruction.  

Will Russia’s current nuclear weapons levels increase like the cobras in India? It is unknown, but regardless, the argument for the dome is strong. An imperfect defense would still complicate Russia’s planning and could improve protection against limited or accidental launches. Golden Dome could make America safer, however there is risk that it may do the opposite; no one can yet say. However, uncertainty is not a reason to abandon the concept, but a reason to keep exploring and to field it once it is ready. The dangers are not diminishing, and the world is growing less predictable. A nation must mitigate the dangers that exist and find a way not to release the bounty on the cobras.

Would Golden Dome Make America Safer? was originally published on Global Security Review.

The ongoing conflict involving Iran, the United States, and Israel has produced one of the most significant case studies in the evolution of contemporary warfare. Iran, a state that lacks a competitive air force and possesses limited naval power, has demonstrated that ballistic missiles, cruise missiles, and unmanned aerial systems can offset some conventional disadvantages and impose serious costs on technologically superior adversaries. This development is not confined to the battlefield. It represents a doctrinal shift with lasting implications for American deterrence strategy, allied defense planning, and the long-term viability of current U.S. force structures. Understanding what Iran has and has not achieved is essential for making sound policy going forward.

The Cost-Exchange Problem 

At the operational level, Iran’s most consequential contribution has been exposing a structural vulnerability in layered air defense: the cost-exchange dilemma. Systems such as Patriot, THAAD, and Iron Dome were engineered to intercept high-value ballistic and cruise missile threats. When deployed against coordinated waves of low-cost drones and short-range missiles, these systems are forced to expend interceptors valued at hundreds of thousands or millions of dollars per shot against threats that cost a fraction of that amount. The arithmetic is unsustainable at scale. As analysts at the Center for Strategic and International Studies have noted, saturation attacks can exhaust defensive inventories faster than replenishment is possible, creating windows of vulnerability that adversaries are quick to exploit. For the United States, this is not merely a technical problem, it is a strategic one that requires urgent attention in both procurement and doctrine.

The development of the Golden Dome missile defense architecture and expanded investment in directed energy and electronic warfare systems reflect growing official awareness that current interception models are not cost-competitive. These are necessary steps. However, technology alone cannot resolve a dilemma that is fundamentally about the economics of offense versus defense. Adversaries will adapt their tactics faster than procurement cycles can respond unless the U.S. also changes the strategic logic driving their calculations.

Attrition Without Decision: The Limits of the Iranian Model

The Iranian approach has imposed genuine costs on its adversaries, but it has not produced decisive military outcomes. This distinction is critical. Iran’s missile and drone campaigns have disrupted logistics, strained defensive inventories, and created operational uncertainty. They have not, however, defeated U.S. or Israeli military power, seized or held territory, or forced a negotiated settlement on Iranian terms. The model is one of strategic attrition, not strategic victory. Survivability and persistence are not equivalent to effectiveness, and the broader narrative of a drone revolution rendering conventional military power obsolete requires significant qualification.

The claim that air superiority is no longer a necessary condition for strategic effectiveness also warrants scrutiny. Air superiority remains essential for intelligence, surveillance, and reconnaissance; for close air support of ground operations; and for denying adversaries freedom of movement. What Iran’s campaign demonstrates is that a state without air superiority can still impose costs and delay adversary operations—not that air power has been rendered irrelevant. The bar for what air superiority can guarantee has been raised. Its strategic value, however, has not disappeared. Policymakers and analysts should resist the temptation to draw sweeping conclusions from a conflict that remains ongoing and whose full operational record is still emerging.

Implications for American Deterrence

The proliferation of precision strike capabilities across state and non-state actors undermines the assumption that technological overmatch alone is sufficient to deter conflict. When adversaries can field asymmetric capabilities that challenge U.S. and allied defenses at an acceptable cost to themselves, deterrence by denial becomes increasingly difficult to guarantee. The U.S. must prioritize cost-effective interception technologies, particularly directed energy weapons, that can neutralize mass drone and missile attacks without depleting high-value interceptor stocks. This is a resource allocation problem as much as it is an engineering one, and it demands serious engagement at the budgetary and strategic planning levels.

The Iranian model is also exportable, and this may prove to be its most consequential long-term dimension. States with limited defense budgets that are aligned with China or Russia can observe the operational lessons from this conflict and apply them in their own regional contexts. The proliferation of domestically produced or externally transferred missile and drone capabilities across the Middle East, South Asia, and the Indo-Pacific represents a compounding deterrence challenge. American extended deterrence commitments to allies in these regions will become harder to sustain if the cost-exchange problem is not structurally resolved. As Defense News reported, the proliferation of drone technology is already forcing militaries worldwide to reconsider their approach to air and missile defense.

There is also a crisis stability dimension that deserves serious attention. Rapid, sustained missile and drone strikes compress decision-making timelines and increase pressure for early, and potentially disproportionate, responses. In a multipolar environment where multiple actors possess similar strike capabilities, the risk of miscalculation is elevated. The U.S. should pursue updated arms control frameworks and diplomatic mechanisms to manage the proliferation of these systems alongside its technical and procurement investments. Deterrence cannot be reduced to hardware alone.

Conclusion

Iran’s missile and drone campaign has not rewritten the principles of warfare, but it has exposed critical assumptions underpinning American deterrence in ways that cannot be ignored. Distributed, low-cost, high-impact systems are now accessible to a wider range of actors and the gap between offensive capability and defensive cost is widening. The United States requires a

deterrence posture that integrates cost-effective defense, credible offensive options, active non-proliferation diplomacy, and sustained alliance management. Meeting this challenge demands strategic adaptation across doctrine, procurement, and diplomacy, not simply an incremental increase in interceptor production.

Iran’s Missile-Drone Campaign and Its Implications for the United States’ Deterrence was originally published on Global Security Review.

By mid-June 2025, after years of preparation, the Israelis, in one fell swoop, destroyed half of Iran’s ballistic missile capabilities, destroyed some nuclear facilities, and assassinated Iran’s leading nuclear scientists and the leadership of the Islamic Revolutionary Guard Corps (IRGC). Then on June 23, 2025, a pre-dawn bombing raid ordered by US President Donald Trump took out of commission the hard-to-crack nuclear facilities of Fordow, Natanz, and Esfahan.

Beyond adding to Israel’s capabilities with American B2 bombers loaded with GBU-57 massive ordnance penetrators, bunkers busters, the bombing cemented American leadership in dealing with the Iran problem. A review of joint Israel-US capabilities helps explain how deterrence in the region is returning and what to expect next.

Since the October 7, 2023, massacre of Israelis by Hamas, an Iranian proxy, Israeli intelligence and military units, all backed by superior defense technology, methodically destroyed Iranian capabilities and supporters. Iran’s “Ring of Fire” utterly failed to achieve Iran’s strategic aims.

Israeli and American space-based intelligence, surveillance, and reconnaissance enabled early warning, target verification, and battle damage assessment. Israel relied on a precision-strike doctrine that is supported by systems like the Ofek, AMOS, and Eros-B space assets. Israel maintained surveillance for dominance above Iranian military and nuclear infrastructures. Iran merely linked its space program to the IRGC.

With multi-layer sensor fusion, Israel integrates Eitan unmanned aerial vehicles (UAV), ELW-2090 airborne warning and control systems, and ground-based radars like the EL/M-2080 Green Pine with satellite data into a national and regional situational awareness (SA) web, shaping strikes and missile defense prioritization. Space-derived situational awareness enables real-time assessment of missile launches, UAV swarm attacks, or asymmetric maritime threats by Iran and proxies operating from the Red Sea or Persian Gulf.

Cyber intelligence, signal intelligence (SIGINT), and electronic warfare form another layer. In the conflict, Israel command, control, communications, and computer (C4) systems pit Unit 8200 against IRGC affiliated cyber units.

Israel’s missile shield includes Iron Dome, David’s Sling, and Arrow-2/Arrow-3. They combine to create a web of coverage. Arrow’s high-altitude, long-range interceptors tackle Iranian ballistic missiles such as Fattah, Shahab, and Sejil. Iron Beam laser defense, under development, aims to address low-cost, high-volume threats like UAVs and small rockets.

Israeli capabilities for missile defense, early warning, C4, and interoperability are integrated with US Central Command and the systems of the Gulf States. The US supports Arrow and David’s Sling. Aegis ballistic missile defense and terminal high altitude area defense (THAAD) systems in the region share radar feeds. American space-based infra-red system satellites provide missile-launch detection.

Bahrain hosts the US Navy and supports regional C4ISR, and has growing maritime security ties with Israel. The US expanded its Saudi Arabian basing in Tabuk to feed into the regional missile defense picture. The United Arab Emirates enables THAAD, Patriot (PAC-3), radar integration, and air picture sharing with the US and Israel. Jordan, the United Kingdom, and France also contribute to defensive actions during missile and drone attacks.

Iranian targets and their proxies have nowhere to hide. The US Space Force’s Space Operations Command Mission Delta 4 identifies and tracks threats. It did so during the April 2024 and October 2024 Iranian missile and drone attacks on Israel. Operating 24 hours a day, 365 days a year to share intelligence, Mission Delta 4 ensures no missile launch ever catches America or her allies and partners by surprise.

A space-enabled Israel, integrated with Gulf State operations, eliminated Iranian air defenses, triggered covert operations inside Iran, and launched targeted bombings and assassinations. The American bombing topped these other efforts. Israel, as the military strong horse, irreversibly altered the regional balance of power, possibly ushering in the demise of a threatening Iranian Shia hegemony—an objective shared by Sunni Arab Gulf States.

Regime change was never a stated war aim but was an anticipated consequence if it occurred. It did not. The surviving Shia Islamist leadership and IRGC are now engaged in repression and remain capable of inflicting much suffering on both the region and Iranians.

It is unclear to which extent proxies such as Hezbollah, the Houthis, and Shia militias can still attack Israel and American assets in the region. Military outcomes, though, are not the sole factors defining the Iranian endgame. The Iranian taqiyya-driven regime and its Shia hegemony ideology are down, but not out. Their nefarious ideological influence can persist around the Gulf, as far as Yemen and Africa, and beyond.

Considering the cost of inaction and a failure to reinstate deterrence, eradicating a threat to the homeland, Middle East bases, and Gulf allies means the effort was worth it. If the conflict drags on, the costs will rise. Disruption of maritime traffic and oil markets could bring its predictable cohort of economic disruptions. Terrorism around the globe is déjà vu.

In the words of German Chancellor Friedrich Merz, “Israel is doing the dirty work for all of us.” Depending on the roles the new Syrian leadership and a resurgent Türkiye play, the Iranian endgame may take different forms.

Yes, President Trump decisively played the hand he was dealt. But there are many more moves left in this game. The best moves may be still to come.
