Still - makes you think what China would be capable of. Their investements into cyber-warfare are said to be immense. That they are aiming at the ability to disrupt civilian infrastructure and energy-systems nation-wide, and probably are capable of that, is known since years.

The dependency on communication networks and satellites I see as a major all-win-or-all-loss strategy since longer. If I were an evil rogue nation with finacial and scientific ressources, I would invest into EMP-capable and anti-satellite weapons as well.
what makes it even more riskier, that forces tend to reduce in size the ore dependent on high technology they are, due to financial arguments. So every major score by the enemy in the high tech field is the more devastating the more high tech your own forces are - because you have fewer material reserves and options to compensate damages.
