This piece summarizes Elisabeth Braw’s examination of the strategic vulnerability posed by the world’s underwater cables and pipelines. It documents a series of deliberate-sounding attacks - most notably the Chinese-flagged Yi Peng 3 cutting undersea cables linking Sweden, Lithuania and Germany in November 2024, Chinese ships severing links to Taiwan’s Matsu islands in 2023, the NewNew Polar Bear’s anchor strikes, and the 2022 Nord Stream sabotage - and places them in a wider pattern of “hybrid attacks” including mysterious fires at defense plants, robotic boats near offshore gas platforms, and alleged Russian-directed arson plots. The scale of the problem is stark: roughly a million miles of communication cable and some 20,000 miles of subsea pipelines knit the global economy, and current legal regimes dating back to 1884 plus UN Law of the Sea rules leave enforcement to the culprit nation, creating near-impunity for state-linked actors.
Braw’s core argument is that these seams of modern life are soft targets that can instantaneously cripple banking, healthcare, communications and commerce, and that policymakers must harden them - chiefly through redundancy such as duplicate cables. The book is presented as a sober, expert survey rather than a thriller: thorough on incidents and legal failings, slightly disjointed on Nord Stream, but clear that persistent undersea hostility is already a feature of contemporary geopolitics and requires urgent, practical fixes.
