NSA Director ADM Mike Rogers said China could take out the US electrical grid.
At a hearing of the House intelligence committee, Rogers said U.S. adversaries are performing electronic "reconnaissance" on a regular basis so that they can be in a position to disrupt the industrial control systems that run everything from chemical facilities to water treatment plants.
"All of that leads me to believe it is only a matter of when, not if, we are going to see something dramatic," he said.
If this doesn't give you a chill, you are not paying enough attention. Our country would start to deteriorate quickly if we lost power, and it's certainly not because we couldn't test each other. Water, transportation, sewage, food, etc. All of our major systems are networked and if you think they are better secured than any other online system, you are sadly mistaken.
We need to do something about this, and sooner is better than doing it later in the dark.
