This illustrates something I'm worried about. Cyber as a battle space, and the extreme vulnerability of some countries negates some of the traditional strategic advantages that superpowers have had. That will rebalance in time. But I worry that for an up and coming power with a kick-ass cyberwarfare operation, there is no better time to start a war than right now.
One saving grace is that if a cyber attack was bad enough, it would likely result in retaliation in the physical space, provided attribution could be proven. Superpowers generally have armed forces far superior to asymmetric attackers and would be able to inflict punitive damages far beyond the cost of the initial cyber attack. There is some deterrence against some of the worst attacks eg: knocking out a power grid.
If you look at the pattern of really nasty cyber attacks against infrastructure and industry, they usually are the other way around. Stuxnet was the US attacking Iran, Ukraine was attacked by Russia.
