This week, the Senate is considering a plan to improve cybersecurity. Its advocates say they want to prevent computer hackers from going after the power grid or other vital infrastructure in this country. Maryland Senator Barbara Mikulski contends a cyberattack could be worse than the freak storm that hit the nation's capital this summer.
The latest national security issue to figure in the presidential campaign has little to do with Iran, Afghanistan or other foreign policy challenges. Mitt Romney is instead focusing on what he and other Republicans allege is the Obama administration's record of leaking classified information for political purposes.
When an experimental U.S. spy plane was shot down over the Soviet Union in 1960, the U.S. government quickly came up with elaborate cover stories.
"The plane [Soviet leader Nikita] Khrushchev reported shot down inside Russian territory presumably is an American, single-engine jet, a U-2 reported missing on a flight along the Turkish-Russian border last Sunday," a broadcast at the time said. "The national space agency has been flying these planes, 10 of them, in many parts of the world, studying the upper atmosphere."
