The Wall Street Journal reported that spies from Russia and China have penetrated the United States power grid. "The intruders haven't sought to damage the power grid or other key infrastructure, but officials warned they could try during a crisis or war," the report said.


Former Terrorism Czar Richard Clarke told ABC's Diane Sawyer that the U.S. should consider disconnecting the power grid from the internet to decrease the likelihood of attack.
