Why NATO Is Watching the Bottom of the Sea

The next crisis might begin with something you never see: a cable on the seabed. Why are Russia, NATO and Europe’s internet connected to the same stretch of water? We go beneath the Baltic Sea to explore the struggle over undersea cables: what access could reveal, what disruption could do, and why proving sabotage is harder than spotting a suspicious ship. From the EstLink 2 power-cable failure to NATO’s Baltic Sentry and the AI-supported Nordic Warden system, this documentary separates documented events from hypothetical scenarios. Cutting a connection, intercepting information and causing a blackout are very different things. Which would you prioritise: more patrols, backup connections or faster repairs?
