ABC News: In an EXCLUSIVE interview on "This Week," host Jake Tapper asked CIA Director Leon Panetta what threat the U.S. is not paying enough attention to. One of his answers: cyber warfare. "We are now in a world in which cyber warfare is very real. It could threaten our grid system. It could threaten our financial system," Panetta said. "It could paralyze this country, and I think that's an area we have to pay a lot more attention to," the CIA chief said.
