multiple simultaneous national actions around submarine cable resilience surfaced in a single cycle: japan embedded cable landing-point diversification into its cabinet growth strategy following baltic sea and taiwan-adjacent incidents; somalia activated a technical working group on cable governance; and a cross-regional analysis explicitly framed the 570-system undersea cable network — carrying 95–99% of international internet traffic — as an active target in great-power competition. the simultaneity of governance responses across geographically unconnected regions in one cycle suggests the cable-as-military-target frame is now being operationalized at national policy level globally.
