Cyber Economic Warfare
Finding
The weakest assumption is that a cable or cyber disruption would defeat alternate routes and payment backups long enough to become a multi-day economic shutdown. The evidence does not yet support that as a general case.
What changed
A new cable-break study finds much smaller estimated losses where countries have diverse international connections; a European payment-system failure shows that backups can fail together, but settlement largely caught up that day.
Decision
Keep the action at **consider**. Do not turn it into a broad investment position now; make a sustained failure of essential services, not a cable break alone, the trigger for reconsideration.
Watch next
Whether alternate network routes, emergency payment capacity and port workarounds actually sustain service through the next serious incident.
