@mttaggart As far as I'm aware there has never been any policy that cyber attacks are treated as fundamentally different to kinetic ones. A lot of the public have this idea in their head that cyber should only be responded to with cyber, but that has never been the case. There is absolutely no difference between a cyber attack on, say, a power grid, and blowing up substations. Both the intent and effect is the same, the means by which the attack is orchestrated literally does not matter at all.
The entire idea of "cyber war" is logically incoherent nonsense imo.
