Geopolitical Implications of Undersea Cable Vulnerability and Digital Infrastructure Warfare

Iran has developed detailed plans to target undersea communication cables in the Gulf, including the Strait of Hormuz and potentially the Red Sea, if the United States and Israel launch renewed attacks. Iranian security officials stated that such attacks would aim to prevent repairs, causing prolonged disruptions to global internet and financial transactions. This threat is seen as a deterrent to renewed conflict and a way to pressure Washington by making Gulf governments and U.S. companies fear for their significant investments in digital infrastructure, including data centers and AI facilities, as they diversify beyond oil. While the Strait of Hormuz carries less than 1% of global bandwidth, the Red Sea is a more significant target. The article highlights the global reliance on undersea cables (carrying ~99% of internet traffic) and the growing need for digital infrastructure resilience, with companies like Microsoft investing in alternative connectivity.
