For what it's worth, that's exactly why it seems like something that is likely to actually happen. It's one thing to threaten mutual nuclear destruction and quite another to give the order to actually kill hundreds of millions of people and almost certainly end or ruin your own life. Since that basically excludes any intentional act by a moral or rational actor, my understanding is that the closest calls were usually cases of mistaken intent. A global internet outage would be devastating for economic and possibly humanitarian reasons, but would not have the degree of practical and moral deterrence that exists for nuclear weapons.
