Iran’s Digital Leverage to Black Out the Globe

Paris (Imran Y. CHOUDHRY) :- Former Press Secretary to the President, Former Press Minister to the Embassy of Pakistan to France, Former MD, SRBC Mr. Qamar Bashir analysis : When President Donald Trump warned that the United States could “destroy the civilization of Iran,” few in Washington imagined that Iran would respond not merely with missiles, drones, or naval blockades, but by exposing a terrifying reality to the world: modern civilization does not only run on oil. It runs on data. And much of that data passes through the same narrow waterway that carries the world’s energy lifeline — the Strait of Hormuz.
For decades, the Strait of Hormuz was viewed primarily as the world’s most critical oil chokepoint connecting the Persian Gulf to the Arabian Sea. Every crisis in the region triggered fears of soaring fuel prices, economic collapse, and shipping paralysis.
But the 2026 Iran-USA-Israel conflict has revealed something even more consequential hidden beneath those waters: the digital nervous system of the modern world.
Beneath the seabed of Hormuz lie at least seven major undersea fiber-optic cable systems, including FALCON, AAE-1, TGN-Gulf, and several Asia-Europe communication routes. These cables carry enormous volumes of global internet traffic, cloud computing operations, banking transactions, military communications, GPS synchronization signals, AI data flows, financial clearing systems, media broadcasts, and commercial operations linking Asia, the Middle East, Europe, and beyond. These are not ordinary cables. They are the arteries of modern civilization.
More than 95 percent of international internet traffic travels through undersea fiber-optic networks. Gulf nations such as Saudi Arabia, the UAE, Qatar, Kuwait, and Bahrain rely heavily on these cables for everything from oil trading and banking to aviation control and national security communications.
India depends on these routes for connectivity to Europe and the Middle East. Global tech giants such as Google, Meta, Amazon, and Microsoft either own, lease, or operate major portions of the world’s subsea cable infrastructure. In reality, the modern internet is not floating in the clouds. It lies vulnerable at the bottom of the ocean.
Iran recognizes this vulnerability and is keeping the option open to impose licensing fees, regulations, and even operational control over the fiber-optic cables passing through Hormuz. Tehran has reportedly explored legal mechanisms to treat the underwater infrastructure as part of Iran’s sovereign jurisdiction within the strait. While the world initially dismissed these statements as propaganda, the strategic implications are staggering.
The closure or disruption of the Strait of Hormuz already pushed oil prices sharply upward, increasing fuel costs for ordinary Americans and consumers worldwide. Many households experienced thousands of dollars in additional annual expenses due to inflation, rising transportation costs, food prices, and energy shocks. But a disruption of the digital cables beneath Hormuz would unleash a crisis far beyond inflation. It would paralyze civilization itself.
The modern financial system depends on millisecond communication between banks, stock exchanges, SWIFT systems, trading platforms, and cloud servers. Trillions of dollars in financial transactions pass daily through these networks. A major cable disruption could halt real-time banking operations, freeze financial markets, delay international transfers, and disrupt payment systems globally. The consequences would not stop there.
Commercial aviation relies heavily on digital communication networks for navigation, weather coordination, GPS synchronization, and air traffic management. Shipping industries use constant data exchanges for cargo tracking, maritime safety, navigation routing, and port logistics. Modern agriculture depends on satellite-linked irrigation systems, weather forecasting, fertilizer supply coordination, commodity exchanges, and precision farming technologies. Hospitals rely on cloud databases and communication systems. Governments rely on encrypted defense communications. Artificial intelligence systems depend on uninterrupted data exchange between global data centers.
If these cables were severely disrupted, much of the modern world could slow to a standstill within hours. Even temporary outages are catastrophically expensive. Studies estimate that major internet disruptions can cost millions of dollars per hour. IT outages alone can cost corporations over $33,000 per minute. Repairing damaged subsea cables can cost between $1.5 million and $8 million depending on the scale of the disruption. But the indirect economic losses are far greater — potentially reaching hundreds of billions or even trillions of dollars if outages persist.
The world received a warning in 2006 when an earthquake damaged nine undersea cables near Taiwan. Connectivity disruptions lasted for weeks across parts of Asia, affecting banking systems, communications, and trade flows. Eleven repair ships required nearly 50 days to fully restore operations. Now imagine a deliberate geopolitical confrontation centered around Hormuz.
Unlike oil tankers, these cables cannot easily be replaced or rerouted overnight. They lie in shallow, vulnerable seabeds where anchors, sabotage operations, or military activity can sever them. Even a few coordinated disruptions could force global internet traffic into severe congestion, creating massive latency, communication failures, and digital blackouts. This is why Iran’s leverage now extends beyond missiles and naval power.
For the first time in modern history, a regional power has demonstrated the ability to influence both the world’s energy bloodstream and its digital nervous system simultaneously.
Iran’s strategic posture has evolved dramatically during this conflict. Initially, Tehran refused discussions on nuclear limitations, missile restrictions, or reopening Hormuz until hostilities ceased permanently and reparations for infrastructure damage, assassinated leadership figures, and civilian casualties were addressed. Iran’s leadership appears convinced that the closure of Hormuz — and the fear surrounding it — forced the world to recognize the limits of American and Israeli power projection.
Now Tehran possesses another negotiating card: the digital cables. The implications for the United States are profound. American military power depends heavily on global communication networks. Command-and-control systems, intelligence sharing, satellite synchronization, drone operations, logistics coordination, and cloud-based defense infrastructure all rely on resilient international data routes. If Iran can influence, disrupt, or regulate these networks near Hormuz, it creates a new layer of strategic vulnerability for Washington.
Even more alarming for Western policymakers is that disruption can occur through hybrid warfare methods. A cable cut caused by “accidental” anchor dragging or proxy sabotage creates plausible deniability while still inflicting enormous damage. Such attacks are harder to deter than conventional missile strikes.
This is why President Trump’s upcoming visit to China carries extraordinary significance. Beyond discussions about trade, tariffs, and geopolitics, one of the most urgent priorities will likely involve restoring stability to the Strait of Hormuz and ensuring the uninterrupted flow of both energy and digital communications.
The reality now confronting the world is sobering. Oil was once considered the single jugular vein of modern civilization. But the 2026 conflict has exposed a second jugular vein hidden beneath the oceans: the global fiber-optic communication network. Together, these two systems power the modern world. And today, Iran sits astride both.
Whether Tehran ultimately uses this leverage for negotiation, deterrence, or economic pressure remains uncertain. What is certain is that the world has entered a new era where wars are no longer fought only with bombs, tanks, and missiles. They are fought through shipping lanes, data cables, cloud infrastructure, financial networks, and communication systems that sustain every aspect of modern life.
If these systems collapse simultaneously, humanity would not simply face recession or inflation. Large parts of civilization could be pushed temporarily into digital darkness — a modern form of the Stone Age in the age of artificial intelligence.
