US Warns of Possible Strikes on Iran as Tehran Threatens Gulf Subsea Cables

The physical infrastructure of the global internet relies on the assumption that the seabed remains a neutral zone—a condition that is now actively contested. Iranian military officials have explicitly threatened to sever subsea communications cables in the Persian Gulf if the United States and Israel launch renewed military strikes against Tehran.[1][2]

The warning marks an unprecedented expansion of potential targets in the ongoing conflict. Rather than focusing solely on traditional energy assets, Tehran is now threatening the digital corridors that carry international financial data and cloud services.[3]

In response to the escalating rhetoric in late October 2026, U.S. officials have warned that strikes on Iranian soil remain a distinct possibility. The U.S. government has already ordered diplomats and federal employees to leave Saudi Arabia, drawing down staff at other regional missions as intelligence indicates Iran is in the advanced stages of planning attacks against Americans.[5]

"If they want to damage our infrastructure, it is natural that the Islamic Republic will use all its power," said Yadollah Javani, the deputy head of political affairs for Iran's Islamic Revolutionary Guard Corps. "Seven important cables that pass under the waters of the Strait of Hormuz will be easily destroyed."[3]

The threats extend beyond the seabed. Mohsen Rezaei, the secretary of Iran's supreme national security council, stated that Tehran would also strike oil facilities, data centers, and artificial intelligence infrastructure across as many as seven Gulf countries if a joint U.S.-Israeli assault proceeds.[1]

Iranian leadership views the warnings as a necessary deterrent against a third war in two years. Mohammed Mokhber, an adviser to Iran's Supreme Leader, dismissed the U.S. and Israeli military posturing as "psychological warfare" and an act of desperation, even as both sides prepare for potential escalation.[4]

Vulnerability of Digital Corridors

The strategic focus on subsea cables highlights a critical vulnerability for Gulf states that have invested heavily in cloud computing and AI hubs. While less than one percent of global internet bandwidth passes through the Strait of Hormuz, regional connectivity and local economies would face severe disruptions if the cables were severed.[2][3]

Telecommunications data indicates that five active submarine cable segments pass through the Strait of Hormuz. These lines primarily serve countries in the Persian Gulf, meaning an attack would pose a direct threat to regional connectivity rather than triggering a global internet shutdown.[2]

Despite the localized impact on global bandwidth, the destruction of these cables would paralyze electronic clearing systems and digital command-and-control centers operated by state-owned energy conglomerates. Gulf governments have spent billions of dollars building massive data centers over the past three years, infrastructure that now sits in the crosshairs.[1]

Repairing damaged cables would prove exceptionally difficult in waters affected by active military operations. Specialized repair vessels would face severe security risks and restrictions on movement, potentially prolonging internet outages and communication disruptions for months.[2]

Escalating Military Posture

As diplomatic negotiations remain deadlocked, the U.S. military continues to map Iranian missile sites and energy installations for potential strikes. Defense officials have briefed about a potential new military campaign that would target missile sites, oil installations, and nuclear sites if deterrence fails.[1]

The saber-rattling by both sides has coincided with extended joint-training maneuvers by the United States and Israel. Dozens of Israeli planes flew close to the Iranian border in late October, signaling readiness for a coordinated assault following the U.S. midterm elections.[1]

Meanwhile, Iran has reinforced defenses around its nuclear sites and other sensitive facilities. The Islamic Revolutionary Guard Corps claimed that three ships had already been struck by naval mines in the Strait of Hormuz, though independent verification remains elusive.[1]

The maritime disruptions have already impacted global markets. Brent crude oil recently traded at $113.40 a barrel, a significant high propelled by reports of the imminent renewed joint Israeli-U.S. assault on Iran and the resulting threats to Gulf energy infrastructure.[1]

Diplomatic Drawdown and Evacuations

The deteriorating security environment has prompted immediate diplomatic consequences. The U.S. State Department's decision to evacuate personnel from Saudi Arabia underscores the perceived imminence of Iranian retaliation against American interests in the region.[5]

U.S. intelligence officials assess that Iran is not merely posturing but is in the advanced stages of operational planning. The withdrawal of federal employees from regional missions reflects a calculation that Gulf states hosting U.S. forces could face direct kinetic strikes.[5]

Iranian officials have framed their threats as a defensive measure against aggression. Mehdi Mohammadi, an adviser to Iran's parliament speaker, stated that the next conflict is viewed as an existential threat, declaring that Tehran's strategy now operates with "zero red lines."[1]

The inclusion of artificial intelligence facilities as military targets marks a significant shift in modern warfare doctrine. By threatening the economic architecture that enables regional development, Tehran aims to pressure Gulf states into constraining U.S. military operations.[1]

The Closing Window for Diplomacy

With both sides entrenched in their positions, the window for de-escalation appears to be closing rapidly. The transformation of the seabed and digital infrastructure into active battlefronts ensures that any renewed conflict will carry unprecedented economic and technological consequences.[1][3]

The threat to subsea cables also complicates the strategic calculus for international technology companies operating in the region. Major cloud providers maintaining large language model training operations in the United Arab Emirates and Qatar now face the prospect of physical destruction of their hardware.[1]

U.S. officials have not publicly detailed how they would protect the undersea infrastructure if hostilities commence. However, the explicit Iranian warnings suggest that any U.S. strike would trigger an immediate asymmetric response aimed at maximizing economic pain for Washington's regional allies.[3][5]

As the standoff continues, the focus remains on whether the threat to digital and energy lifelines will successfully deter a U.S.-Israeli offensive. Until the diplomatic deadlock breaks, the Persian Gulf remains poised on the edge of a conflict that would redefine the boundaries of infrastructural warfare.[1][4]
