Fiber-optic cables and the power struggle underwater

The globe is digitally connected through 750,000 miles of undersea fiber-optic cables. They are vulnerable to accidental disruption like natural disasters or the anchors of ships. But they are also increasingly an arena of competition and sabotage among big powers. Marco Werman discusses those power dynamics with Erin Murphy, a senior fellow for the Asia Program at the Center for Strategic and International Studies and the co-author of a new CSIS report called "Safeguarding Subsea Cables: Protecting Cyber Infrastructure Amid Great Power Competition."
