A hidden network of power cables and pipelines on the ocean floor sustains our world, but it is no longer safe. National security expert Elisabeth Braw and award-winning investigative journalist Bojan Pancevski examine whether control of the deep sea is becoming the next geopolitical frontline. From the Baltic to the Pacific, sinister ruptures, mysterious vessels and submarine incursions point to a conflict already underway, including those examined in Bojan’s reporting on the destruction of the Nord Stream pipeline carrying cheap Russian gas to Europe. In conversation with Julia Wheeler , they discuss the high-stakes fragility of this infrastructure underpinning modern life and how the depths below may shape the future of global security. There will be a book signing after this event . Get ahead of your Festival reading and visit the Waterstones Cheltenham Literature Festival bookshop and support Cheltenham Festivals with every purchase.
