Assessing Iran’s robust retaliation capabilities: How Tehran could respond to a US attack and its global economic implications
Amid persistent geopolitical tensions in the Middle East, the specter of a large-scale conflict involving the United States and Iran continues to fuel global concerns. The recent deployment of a US carrier strike group to the region, coupled with strong warnings from the current American administration about potential military action, underscores the critical escalation risks. For nearly half a century, Iran has meticulously prepared for such a confrontation, developing asymmetric warfare strategies designed to impose significant costs that could destabilize the entire region and ripple through the global economy.
Despite facing considerable challenges, including targeted attacks from regional adversaries and growing domestic unrest, the Iranian regime maintains a diverse array of options for retaliation. These strategies are not geared towards matching conventional American military might but rather towards leveraging strategic vulnerabilities to create a deterrent effect. The nature and intensity of Tehran’s response would largely depend on its perception of the existential threat it faces, according to security analysts.
As Farzin Nadimi, a senior research fellow specializing in Iranian security and defense at the Washington Institute, highlighted, “The regime has many capabilities at its disposal if it sees this as an existential war.” He added, “If they see this as a final war, they might use everything they have.” This perspective indicates a potential for an all-encompassing response if Iran perceives its survival is at stake.
Iran’s advanced missile and drone capabilities
Iran is believed to possess a vast arsenal of thousands of missiles and drones, capable of reaching American forces stationed across various Middle Eastern countries and threatening key allies, notably Israel. These weapons represent a core component of Tehran’s defense strategy, designed to overcome advanced air defense systems through sheer volume and diverse attack vectors.
The effectiveness of these systems was notably demonstrated in recent years. Following a surprise attack attributed to Israel, the Islamic Republic retaliated by launching waves of ballistic missiles and drones that successfully navigated sophisticated air defenses, inflicting damage on targets. Iranian officials assert that their stockpiles have been replenished, and American intelligence indicates these combat-tested weapons, alongside older Russian and American fighter jets, continue to pose a significant threat.
The Iranian-developed Shahed suicide drone, for example, has proven to be a destructive tool in various conflicts worldwide. Tehran has also developed, tested, and deployed over 20 types of ballistic missiles, including systems with short, medium, and long ranges, some capable of striking targets as far as southern Europe. According to Marco Rubio, a US Secretary of State, “We have between 30 and 40 thousand American soldiers stationed in eight or nine facilities in that region. All are within range of thousands of Iranian drones and Iranian (short-range) ballistic missiles that threaten our military presence.”
Mobilizing regional proxy networks
Over the past two years, Israel’s efforts have reportedly weakened Iran’s regional network of allied groups, diminishing Tehran’s capacity to project power beyond its borders. Nevertheless, these proxies remain a critical component of Iran’s defense strategy and have pledged their allegiance and readiness to assist the Islamic Republic if it comes under attack.
Key groups, such as Iraq’s Kataeb Hezbollah and Harakat al-Nujaba—militias with a history of targeting US forces—along with Lebanon’s Hezbollah, have publicly affirmed their commitment to aid Iran. Abu Hussein al-Hamidawi, a commander of Kataeb Hezbollah, specifically called upon Iran’s supporters worldwide to prepare for a comprehensive war in defense of the Islamic Republic.
Despite these threats, the capabilities of Iran-backed groups are not without limitations. In Lebanon, Hezbollah has been significantly weakened by ongoing regional conflicts and faces increasing internal pressure regarding its disarmament. Similarly, Iraqi militias, while powerful, operate under a central government that is increasingly pressured by the United States to curb Iranian influence within its borders. The Houthi group in Yemen, though targeted by both Israel and the US, remains one of Iran’s most destructive proxies and has repeatedly signaled its willingness to defend its patron, demonstrated by recent provocative actions involving shipping in crucial waterways.
The strategic leverage of the Strait of Hormuz
Iran has consistently warned that any conflict would not be confined to the Middle East but would have profound global repercussions. While conventionally outmatched, Tehran possesses a unique strategic advantage in its ability to disrupt global energy markets and international trade from one of the planet’s most sensitive regions. The country, a major energy producer, is strategically situated along the Strait of Hormuz, a narrow maritime chokepoint through which over a fifth of the world’s petroleum and a significant portion of its liquefied natural gas flows daily. The Iranian regime has repeatedly threatened to close this vital waterway if attacked, a move experts warn could cause global fuel prices to skyrocket far beyond Iran’s borders and potentially trigger a worldwide economic recession.
Economic repercussions and global stability
Analysts suggest that targeting the global economy via the Strait of Hormuz could be among Iran’s most effective, yet perilous, options. The widespread impact of such a measure would be unprecedented. A prolonged closure of the strait represents a “dangerous scenario,” according to Umud Shokri, a Washington D.C.-based energy strategist.
Even partial interruptions could lead to sharp price increases, disrupt supply chains, and amplify global inflation. In such a scenario, a global recession would be a significant and immediate risk. This drastic measure would likely be considered a last resort for Iran, as it would severely damage its own trade and that of neighboring Arab states, many of whom have previously opposed American military action against Iran and committed to denying Washington access to their territories for an attack.
Tehran’s long-term defense strategy
The Iranian regime claims to possess extensive underground naval bases along its coastline, housing dozens of fast attack boats ready for deployment in the Persian Gulf waters. Over three decades, the military has meticulously built its own fleet of ships and submarines, with production accelerating in recent years in anticipation of potential naval confrontations.
US assessments and deterrents
Vice Commander of US Central Command, Robert Harward, has acknowledged that Iranian naval capabilities, along with those of its allies, present a challenge to navigation in the Strait of Hormuz. While he suggests these challenges “can be resolved very quickly,” he also points out that tools such as mines, drones, and other unconventional tactics could indeed pose a significant threat to maritime navigation and the unimpeded flow of oil. American officials have indicated that Tehran’s military capabilities, even if numerically inferior and older than modern US systems, would make a decisive American attack on the country considerably more complex and difficult to execute. Furthermore, Tehran has repeatedly warned it would retaliate against US allies in the region if attacked, a threat demonstrated by past missile strikes on US military installations in response to perceived aggressions.
