The Red Sea Crisis of 2024: Houthi Shipping Attacks and Suez Disruptions

Historical Context and Origins

The crisis that erupted in the Red Sea in late 2023 and escalated into 2024 is not an isolated event but the culmination of nearly a decade of regional volatility and centuries of geopolitical contestation over vital maritime passages. The Houthi movement—formally known as Ansar Allah (Supporters of God)—rose to prominence during the Yemeni Civil War that began in 2014, evolving from a marginalized Zaydi Shia religious revivalist group in northern Yemen into a formidable military and political force.

Rooted in the mountainous northern province of Saada, the Houthi movement emerged in the 1990s as a response to perceived Saudi Wahhabist influence and the marginalization of Yemen's Zaydi Shia minority by the central government. Its founder, Hussein al-Houthi, articulated an ideology blending Zaydi Islam with anti-American and anti-Israeli sentiments, adopting the slogan, "God is the greatest, death to America, death to Israel, a curse upon the Jews, victory to Islam." Following Hussein al-Houthi's death in 2004, his brother, Abdul-Malik al-Houthi, assumed leadership, transforming the group from a local insurgency into a disciplined, militarily capable organization.

The 2014 Houthi takeover of Sana'a, Yemen's capital, and the subsequent 2015 intervention by a Saudi-led coalition, fundamentally reshaped the group's trajectory. Facing a devastating air and ground campaign, the Houthis forged a deeper alliance with the Islamic Republic of Iran, becoming a central player in Tehran's "Axis of Resistance." This network of proxies—including Hezbollah in Lebanon, various Iraqi Shia militias, and Hamas in Gaza—aims to challenge US and Israeli influence in the Middle East. Iranian support, initially limited to training and ideological guidance, expanded to include sophisticated weaponry, including ballistic missiles, cruise missiles, anti-ship missiles, and advanced drones. This infusion of technology, combined with years of asymmetric warfare experience, enabled the Houthis to project power far beyond their traditional operational areas.

The strategic importance of the Red Sea has long been a source of geopolitical anxiety and global competition. The Bab el-Mandeb Strait, Arabic for "Gate of Tears," a narrow waterway a mere 18 miles wide at its narrowest point between Yemen and Djibouti, acts as the crucial southern gateway to the Suez Canal. Historically, this chokepoint has been vital for trade between Asia, Africa, and Europe since antiquity. In the modern era, it serves as a critical artery for global energy supplies and container traffic. Approximately 12% of global trade and 30% of global container traffic transits this strait annually, linking the Indian Ocean with the Mediterranean via the Suez Canal. For the Houthi leadership, controlling or, more accurately, the ability to menace this maritime corridor, provides an asymmetrical advantage that far outweighs their conventional military standing. By leveraging Iranian-supplied loitering munitions, anti-ship ballistic missiles (ASBMs), anti-ship cruise missiles (ASCMs), and reconnaissance drones, the Houthis transitioned from a regional insurgent group into a credible maritime power capable of holding global supply chains hostage. Their actions represent a novel form of asymmetric warfare, where a non-state actor can leverage advanced, relatively low-cost weaponry to impose significant economic and strategic costs on global powers.

Historical Precedents & Context

The Red Sea crisis, while unique in its modern manifestation with advanced drone and missile technology, draws significant parallels from a longer historical narrative of maritime chokepoint vulnerabilities and regional power struggles impacting global trade. Understanding these precedents illuminates the enduring geopolitical dynamics at play.

One of the most frequently cited comparisons is the "Tanker War" of the 1980s, a phase of the Iran-Iraq War (1980-1988). During this conflict, both Iran and Iraq targeted each other's oil exports and merchant shipping in the Persian Gulf to cripple their respective economies. Attacks escalated dramatically, forcing international naval powers, including the United States, to deploy escort convoys (e.g., Operation Earnest Will) to protect neutral vessels. Much like the Houthi attacks, the Tanker War demonstrated how commercial shipping can become a secondary, yet crucial, theater for regional conflicts, drawing in external powers and threatening global economic stability. Key similarities include:

• Targeting Commercial Shipping: Both instances involved deliberate attacks on merchant vessels unrelated to the direct conflict.
• Chokepoint Vulnerability: The Strait of Hormuz in the 1980s, like Bab el-Mandeb today, proved to be an easily weaponized maritime chokepoint.
• Asymmetric Tactics: Iran, in particular, used smaller naval vessels, mines, and anti-ship missiles against larger, conventional forces.
• International Response: The need for international naval coalitions to protect freedom of navigation.

Beyond the Tanker War, the Red Sea's history is replete with instances of maritime insecurity. For centuries, the region was a hotbed of piracy, ranging from local raiders preying on ancient dhows to more organized pirate groups in the modern era, particularly off the coast of Somalia. While the Houthi attacks are fundamentally different in motivation and capability from traditional piracy, they share the characteristic of disrupting safe passage through a critical waterway. The 2008-2012 Somali piracy surge, which also led to significant rerouting of ships around the Cape of Good Hope, underscores the persistent vulnerability of the Horn of Africa and Arabian Peninsula maritime domain.

Furthermore, geopolitical tensions have frequently manifested in the Red Sea. During the Cold War, both superpowers recognized the strategic importance of the Suez Canal and its approaches, leading to military bases and proxy conflicts in surrounding states like Yemen, Ethiopia, and Somalia. The closure of the Suez Canal after the 1956 and 1967 Arab-Israeli Wars dramatically illustrated the economic fragility of reliance on this single waterway, forcing a global re-evaluation of shipping routes and logistics. The longer-term impact was a push for larger supertankers capable of economically navigating the Cape of Good Hope, even with the Suez open.

The present crisis thus represents a confluence of these historical threads: the weaponization of a critical maritime chokepoint, the deployment of sophisticated asymmetric capabilities by a non-state actor, and the complex entanglement of regional proxy warfare with broader international security and economic interests. It is a modern reiteration of ancient vulnerabilities, amplified by contemporary technology and intertwined with ideological conflicts.

Timeline of Events and Key Moments

The escalation from sporadic threats to systematic disruption in the Red Sea moved with alarming speed, reflecting a calculated strategy by the Houthi movement and a reactive, yet resolute, response from international maritime powers.

The seizure of the Galaxy Leader served as a tactical proof-of-concept, demonstrating the Houthis' intent and capability to engage in physical boarding operations. However, this method was soon largely replaced by long-range missile and drone barrages as international navies increased their patrol presence. The Biden administration’s decision to launch Operation Prosperity Guardian was a strategic pivot intended to provide a collective security framework, involving a coalition of nations to intercept projectiles and safeguard transit. This multilateral approach sought to legitimize the response and distribute the burden of security, though the operational commitment varied significantly among participating nations.

Geopolitical Consequences and Aftermath

The Red Sea crisis of 2024 swiftly reverberated across global markets and complex geopolitical fault lines, generating immediate economic fallout and prompting a profound reassessment of international maritime security paradigms.

Economic Fallout and Global Supply Chain Disruption

The economic fallout was immediate and profound. Major shipping conglomerates, including Maersk, Mediterranean Shipping Company (MSC), Hapag-Lloyd, CMA CGM, and Evergreen, redirected their fleets around the Cape of Good Hope at the southern tip of Africa. This unprecedented diversion for such a significant volume of traffic added approximately 3,000 to 4,000 nautical miles (5,500 to 7,400 kilometers) to the journey between Asia and Northern Europe, increasing transit times by 7 to 14 days. The consequences were multifaceted:

• Increased Costs: Fuel consumption surged dramatically, leading to millions of dollars in additional expenses per voyage. Insurance premiums for vessels transiting the Red Sea soared by as much as 500-1000% for war risk coverage, even for vessels that ultimately rerouted. These costs were quickly passed on to consumers.
• Supply Chain Delays: Extended transit times disrupted just-in-time inventory systems, creating bottlenecks and delaying the delivery of goods ranging from consumer electronics and apparel to industrial components and automotive parts. Factories reliant on specific inbound shipments faced production slowdowns.
• Inflationary Pressures: The rising cost of shipping contributed to inflationary pressures in consumer prices, particularly in Europe, which is heavily reliant on Asian imports. Analysts estimated a potential increase in global inflation by 0.2-0.5 percentage points if the crisis persisted.
• Impact on Specific Industries: The automotive industry, with its intricate global supply chains, was particularly vulnerable, facing delays in critical parts. Retailers braced for potential stock shortages and higher prices.
• Suez Canal Revenue Losses: The Suez Canal Authority, a vital revenue generator for Egypt, experienced a significant drop in traffic and earnings as ships diverted, exacerbating Egypt's already precarious economic situation.

Regional Dynamics and Fractured Responses

Beyond the financial metrics, the crisis profoundly impacted regional dynamics, exposing and exacerbating existing divisions. While the US and UK provided the bulk of the firepower for the airstrikes and continued interdictions, several regional partners remained conspicuously silent or hesitant to join Operation Prosperity Guardian. This reluctance stemmed from a complex interplay of factors:

• Gaza Conflict Sympathy: Many Arab nations, including Saudi Arabia, the United Arab Emirates (UAE), and Egypt, faced intense domestic pressure to express solidarity with Palestinians in Gaza. Directly participating in a US-led military operation against the Houthis, who framed their actions as supporting Gaza, risked alienating their populations and being perceived as aligning with Western interests against a perceived "Axis of Resistance."
• Fear of Escalation: Regional powers, particularly Saudi Arabia and the UAE, had only recently de-escalated their involvement in the Yemeni Civil War and engaged in direct talks with the Houthis. Joining a new military campaign against the Houthis risked reigniting regional conflicts and jeopardizing fragile peace efforts. They prioritized stability on their borders over immediate maritime security.
• Strategic Autonomy: Some European nations, such as France and Italy, while condemning Houthi attacks, opted for independent naval deployments rather than integrating fully into OPG, seeking to maintain strategic autonomy and avoid being drawn into potential broader US-Iran confrontations. This fragmented response underscored the challenges of forging unified international action.
• Impact on Abraham Accords: The crisis also strained the normalization efforts between Israel and some Arab states. The Houthis' actions, ostensibly in support of Palestine, appealed to a broad segment of the Arab public, making overt cooperation with Israel or its Western allies more politically fraught for signatories of the Abraham Accords.

International Law and Norms Under Threat

The Houthi attacks represented a direct challenge to the established international maritime order and the fundamental principle of freedom of navigation, enshrined in the United Nations Convention on the Law of the Sea (UNCLOS). The targeting of commercial vessels in international waters by a non-state actor constituted an act of aggression that demanded a robust international response. The United Nations Security Council passed Resolution 2722 in January 2024, explicitly demanding an immediate cessation of Houthi attacks and affirming the right of member states to defend their vessels. However, the resolution's implementation and the varied responses highlighted the limitations of international consensus when geopolitical interests diverge. The crisis forced a re-evaluation of how global commons are secured in an era where non-state actors wield state-level military capabilities and operate with relative impunity within a complex, interconnected conflict zone.

Socio-Economic Aftermath and Global Supply Chain Rethink

The Red Sea crisis transcended immediate geopolitical maneuvering and economic disruption, triggering a significant and potentially long-lasting reassessment of global supply chain resilience, logistics strategies, and the very architecture of international trade. The systemic vulnerabilities exposed by the crisis forced industries worldwide to confront the perils of over-reliance on single chokepoints and the fragility of just-in-time inventory models.

Reshaping Global Logistics and Supply Chain Strategy

For decades, businesses optimized supply chains for efficiency and cost reduction, often prioritizing speed and minimal inventory through methodologies like "just-in-time" (JIT) manufacturing. The Red Sea crisis delivered a stark wake-up call, demonstrating that geopolitical instability can rapidly undermine these efficiencies. The extended transit times, increased freight rates, and exorbitant insurance premiums imposed by the crisis have compelled a fundamental rethink:

• Diversification of Shipping Routes: While the Cape of Good Hope reroute was a default emergency measure, companies are now exploring more permanent route diversification strategies. This could include greater use of rail freight across Eurasia (e.g., the "Belt and Road Initiative" land corridors), although these routes have their own geopolitical complexities and capacity limitations.
• Nearshoring/Reshoring Debates: The crisis reignited discussions about nearshoring or reshoring production closer to end markets. Reducing reliance on long-distance maritime shipping could mitigate risks associated with chokepoints and geopolitical conflicts, albeit often at a higher production cost.
• Inventory Buffers: Companies are re-evaluating their JIT strategies, considering the maintenance of larger "safety stock" or inventory buffers to absorb supply chain shocks. This shift, while increasing warehousing costs, provides greater resilience against unforeseen disruptions.
• Digitalization and Visibility: The need for enhanced supply chain visibility, leveraging digital tools and real-time tracking, has become paramount. Better data allows companies to react more swiftly to disruptions and make informed decisions about rerouting or alternative sourcing.
• Carrier Strategies: Shipping lines themselves are facing immense pressure. The crisis has highlighted the need for greater flexibility in fleet deployment, the potential for building larger vessels capable of economical long-haul routes around Africa, and the imperative for enhanced security measures.

Impact on Consumer Prices and Inflationary Trends

The immediate and secondary impacts on shipping costs have a direct correlation with consumer prices. While the global economy had just begun to recover from the post-pandemic inflationary surge, the Red Sea crisis introduced a new inflationary impulse. Analysts estimated that the added cost of shipping could increase global inflation by a noticeable margin, particularly in import-dependent economies. Goods that are bulky, low-value-to-weight ratio, or produced with tight margins are most susceptible to price increases. This economic pressure compounds the challenges faced by central banks worldwide in managing monetary policy and achieving price stability. The crisis underscored how regional conflicts, even when seemingly geographically distant, can have pervasive effects on the global cost of living.

Environmental Considerations

The rerouting of thousands of vessels around the Cape of Good Hope also carries significant environmental implications. Longer journeys mean substantially increased fuel consumption and, consequently, a greater output of greenhouse gas emissions. This development stands in stark contrast to global efforts to decarbonize the shipping industry and reduce its environmental footprint. The crisis implicitly demonstrated the trade-off between economic efficiency, security, and environmental sustainability in global logistics. The question of how to balance these competing priorities in a volatile geopolitical landscape remains a critical challenge for policymakers and industry leaders alike.

Analysis of Key Actors and Decisive Actions

The Red Sea crisis served as a crucible for the strategic doctrines and operational capabilities of the primary actors, revealing both strengths and limitations in an evolving geopolitical landscape.

The United States and the Biden Doctrine

The response from the administration of Joe Biden was characterized by a delicate balancing act, navigating the imperative to protect global commerce and uphold the principle of freedom of navigation against the formidable challenge of preventing the conflict in Gaza from escalating into a regionalized Middle Eastern war. This approach reflected a blend of deterrence and de-escalation, seeking to punish Houthi aggression without triggering a wider confrontation with Iran.

• Strategic Calculus: The decision to launch "surgical" airstrikes in January 2024 was underpinned by a doctrine of limited kinetic response. The aim was to degrade Houthi capabilities—targeting missile and drone launch sites, radar installations, and storage facilities in Yemen—without attempting a full-scale ground invasion or regime change, which would have likely been seen as a strategic quagmire. Lessons from prolonged engagements in Iraq and Afghanistan weighed heavily on policymakers, emphasizing the need to avoid open-ended military commitments in complex, non-state conflicts.
• Coalition Building (Operation Prosperity Guardian): The formation of OPG aimed to internationalize the burden of maritime security, presenting a unified front against Houthi aggression. While the US and UK provided the bulk of the offensive capabilities, the coalition's composition highlighted both successes and challenges. The participation of Bahrain, a regional Arab partner, was a diplomatic win. However, the reluctance of many European and regional states to commit substantial resources or even publicly associate with the operation—often due to domestic political sensitivities concerning the Gaza conflict or a desire to avoid direct confrontation with Iran—underscored the limits of US leadership in a multipolar world.
• Deterrence and Escalation Management: The Biden administration faced a difficult choice: insufficient response risked emboldening the Houthis and further destabilizing maritime trade, while an overly aggressive response could trigger Iranian retaliation or a wider regional war. The intermittent nature of US and UK strikes, followed by explicit warnings, sought to establish clear red lines while signaling a desire to de-escalate if Houthi attacks ceased. The redesignation of the Houthis as Specially Designated Global Terrorists (SDGTs) aimed to increase diplomatic and financial pressure without fully severing humanitarian aid channels, a nuanced approach to an intractable problem.
• Domestic Reaction: Domestically, the administration faced bipartisan pressure. Some critics argued for a stronger, more decisive military response to immediately neutralize the Houthi threat, while others cautioned against entanglement in another Middle Eastern conflict and questioned the efficacy of airstrikes alone. The financial cost of interdictions, with multi-million dollar missiles used to counter low-cost drones, also became a point of public discussion.

The Houthi Leadership and Strategic Objectives

Under the command of Abdul-Malik al-Houthi, the Houthi movement has demonstrated a sophisticated understanding of asymmetric warfare and strategic communication. Their actions in the Red Sea were not random acts of violence but a calculated maneuver designed to achieve multiple objectives:

• Bolstering Domestic Legitimacy: By framing their maritime blockade as a principled stand against Western-backed Israeli military actions in Gaza, the Houthis managed to rally support across a fractured Yemeni society. Their narrative positioned them as defenders of Palestinian rights and champions against perceived Western imperialism, significantly enhancing their domestic legitimacy and diverting attention from internal governance issues in Yemen.
• Asserting Regional Influence: The crisis dramatically elevated the Houthis' profile from a civil war faction to a significant regional actor capable of impacting global trade. This projection of power served to establish their credentials within the "Axis of Resistance," demonstrating their utility as a potent proxy for Iran and increasing their leverage in any future peace negotiations concerning Yemen.
• Economic Coercion: Their methodology reflected a sophisticated understanding of Western sensitivities: they largely avoided sinking ships outright—which would risk triggering a full-scale war and potentially direct Western intervention on Yemeni soil—and instead focused on creating enough "fear and friction." By forcing rerouting, increasing insurance costs, and causing delays, they aimed to inflict economic pain on Israel and its Western allies, believing this pressure would translate into policy shifts regarding Gaza.
• Asymmetric Advantage: The Houthis leveraged Iranian-supplied weaponry—including loitering munitions, anti-ship ballistic missiles, and advanced drones—to great effect. These relatively low-cost assets, combined with mobile launch platforms and operating from a mountainous, heavily fortified territory, provided them with an asymmetric advantage against technologically superior conventional naval forces. Their ability to absorb initial strikes and continue operations underscored the challenge of eradicating a decentralized, adaptive non-state actor.
• Ideological Alignment (Axis of Resistance): The Houthis' actions were deeply intertwined with the broader Iranian-led "Axis of Resistance." While maintaining a degree of operational autonomy, their strategic objectives often align with Iran's goal of challenging Western influence and exerting pressure on Israel. The crisis provided a clear demonstration of how Iran can utilize its proxies to project power and destabilize critical regions without direct military engagement.

Geopolitical Realignment and Long-Term Legacy

The Red Sea crisis of 2024 is more than a fleeting incident; it represents a significant inflection point with profound implications for geopolitical alignments, global security doctrines, and the future of maritime trade. Its long-term legacy is likely to be a more fragmented, risk-averse, and potentially multipolar approach to global commons.

The Erosion of Maritime Hegemony and Multilateralism

The crisis starkly exposed the limits of traditional maritime hegemony, particularly that of the United States. While the US Navy remains the world's most powerful, the ability of a non-state actor, albeit one backed by Iran, to effectively disrupt a critical global chokepoint for months on end challenged the perception of unchallenged naval dominance. This erosion of perceived security fosters a more cautious approach among commercial entities and forces a reconsideration of the efficacy of conventional deterrence against asymmetric threats.

Furthermore, the varied and often hesitant response from international partners highlighted the increasing difficulty of forging robust, unified multilateral coalitions for collective security. The divisions within the Red Sea coalition reflect broader geopolitical fragmentations, where national interests, domestic political considerations, and differing assessments of the Gaza conflict overshadowed the universal principle of freedom of navigation. This could lead to:

• Regionalized Security Architectures: A trend towards more localized or regionalized security initiatives, potentially involving new alliances or increased self-reliance for maritime defense by affected nations.
• Increased Naval Modernization: Coastal states along vital chokepoints may accelerate naval modernization programs, focusing on anti-drone and anti-missile capabilities.
• Shifting Spheres of Influence: The crisis created opportunities for other global powers, particularly China, to potentially expand their security footprint in the region, offering alternative security frameworks or leveraging their economic influence.

Redefining the "Axis of Resistance"

For Iran and its "Axis of Resistance," the Red Sea crisis was a strategic success in demonstrating their collective power and reach. The Houthis' ability to sustain attacks despite international pressure solidified their position as a key player within this network and showcased the effectiveness of Iran's proxy strategy. This success will likely embolden other non-state actors and further entrench Iran's doctrine of asymmetric warfare, where regional proxies can inflict disproportionate costs on adversaries without direct confrontation. The crisis underscored that future conflicts in the Middle East will likely involve hybrid warfare, blending conventional military action with the use of proxies, cyberattacks, and economic coercion.

Long-Term Economic and Supply Chain Transformation

Beyond immediate costs, the crisis initiated a fundamental shift in how global businesses perceive and manage risk. The legacy will likely be a permanent recalibration of supply chain strategies:

• Resilience over Efficiency: A long-term shift from "just-in-time" to "just-in-case" inventory management, prioritizing resilience and redundancy over absolute cost efficiency.
• Geographic Diversification: Increased efforts to diversify sourcing, manufacturing, and shipping routes to reduce reliance on any single region or chokepoint.
• Investment in Infrastructure: Potential increased investment in alternative transportation infrastructure, such as cross-continental rail networks, or even Arctic shipping routes as climate change progresses, although these come with their own challenges.
• Increased Cost of Global Trade: The era of ultra-cheap, predictable global shipping might be drawing to a close. Increased insurance, security, and logistical costs will likely become embedded in the price of international trade.

Implications for International Law and Governance

The crisis raised complex questions about the application and enforcement of international maritime law against non-state actors operating with state-level capabilities. How does the international community effectively deter and punish such actions without resorting to escalatory military interventions? The incident may spur discussions on updating international legal frameworks to better address hybrid threats and the weaponization of global commons by non-state proxies. It underscores a growing governance gap in the globalized world, where traditional state-centric legal structures struggle to contain contemporary security challenges.

In sum, the Red Sea crisis of 2024 is a testament to the interconnectedness of the modern world, where localized conflicts can generate global tremors. Its legacy will be a more cautious, fragmented, and perhaps more expensive global trade environment, profoundly reshaping geopolitical priorities and the very nature of international security in the 21st century.

Trivia and Lesser-Known Facts

• The "Cape" Premium: During the height of the crisis, the price of a standard 40-foot container shipment from Asia to Northern Europe saw price spikes of nearly 200% to 300% on some routes, with some spot rates climbing from around $2,000 to over $10,000.
• Drone Cost-Efficiency Paradox: Analysts have repeatedly highlighted the extreme asymmetry in the cost of engagement. A Houthi drone or basic anti-ship missile, costing a few thousand to tens of thousands of dollars, often necessitates the use of a multi-million dollar interceptor missile (e.g., SM-2 or Aster) from a US or British destroyer, creating a significant economic burden for the defending forces.
• The UN’s Position: The United Nations Security Council passed Resolution 2722 in January 2024, explicitly demanding an immediate cessation of Houthi attacks, marking a rare moment of near-consensus regarding the illegality of the maritime targeting. However, the resolution notably lacked an enforcement mechanism beyond reaffirming states' rights to self-defense.
• Historical Echoes: The crisis is frequently compared to the "Tanker War" of the 1980s during the Iran-Iraq War, where commercial shipping became a secondary theater for regional power struggles, illustrating a cyclical vulnerability of vital maritime chokepoints.
• "Ghost Ships" and AIS Disruption: Some vessels, particularly those with perceived Israeli connections or those wishing to avoid Houthi targeting, resorted to turning off their Automatic Identification System (AIS) transponders, making them "ghost ships" on tracking maps. This practice, while reducing visibility to threats, also poses significant safety risks in busy shipping lanes.
• Egyptian Economic Impact: The Suez Canal, a critical source of foreign currency for Egypt, saw its revenues plummet by as much as 40-50% in the immediate aftermath of the diversions. This loss further exacerbated Egypt's severe economic challenges.
• Environmental Toll: The rerouting around the Cape of Good Hope significantly increased the carbon footprint of global shipping. Longer journeys mean burning considerably more heavy fuel oil, adding to greenhouse gas emissions at a time when the shipping industry is under pressure to decarbonize.
• The "Houthi Missile Arsenal": While Iranian-supplied, the Houthis have demonstrated an impressive ability to assemble, modify, and even locally produce various drones and missiles, showcasing a sophisticated reverse-engineering and manufacturing capability developed over years of conflict.
• Early Warnings: Prior to the full-blown crisis, various intelligence agencies and maritime security firms had issued warnings about the Houthis' growing anti-ship capabilities, even conducting exercises with Iranian-provided systems. However, the scale and persistence of the actual attacks surprised many.
