Richard Clarke says China has hacked every major US company

Richard Clarke, a former cybersecurity and cyberterrorism advisor for the White House, was a U.S. government employee for 30 years: between 1973 and 2003. He worked during the times of Ronald Reagan, George H.W. Bush, Bill Clinton, and even George W. Bush. 

Clarke now wants to warn us, urgently, that we are being failed again, being left defenseless against a cyberattack that could bring down our nation’s entire electronic infrastructure, including the power grid, banking and telecommunications, and even our military command system.
