Importance of underseas cables to national security and economy could make attacks on cables destabilizing
[ Page 235 ]
Given the likely economic and military impacts of cable breaks, the ability to threaten or protect submarine cables and their shore landings will be increasingly important in future conflicts. In a crisis, an aggressor could use multiple coordinated attacks on cables to compel an opponent to back down or employ them as part of an opening offensive to cut off the defender’s military forces from national commanders, intelligence data, and sensor information. Cable attacks could also be highly destabilizing, since they could prevent a nuclear-armed opponent from controlling and monitoring its strategic weapons and early-warning systems. In response, the country targeted could choose to place its nuclear weapons in a higher alert condition – or initiate a preemptive attack.
Currently the vital U.S. underseas cable industry has to rely on the outdated 1884 telegraph treaty for its legal basis when defending its rights to lay, maintain, and repair underseas cables. U.S. ratification of UNCLOS would better protect U.S. companies’ existing cable systems and foster additional investments by giving telecommunications the legal certainty to their claims that they need.
