Rogers said that those countries regular perform "reconnaissance" on our nations control systems to learn their weaknesses. Because of this, he says, it is not a matter of "if," but of "when" a major catastrophe could happen.
Of course, the US is also capable of doing the same thing to other nations. Rogers says that their knowledge of this should lead to mutual deterrence, but it is not guaranteed. An individual could also do it as well.
The matter of China's stealing industrial intelligence from US computers was also brought up. Rogers said that there really are no practical deterrents in place to stop them, and it is causing future economic problems for the US.
