Reminder of the Impact of an EMP Attack

Investors Business Daily reminds us:
Expert testimony before Congress on Thursday warned that an electromagnetic pulse attack on our power grid and electronic infrastructure could leave most Americans dead and the U.S. in another century. 
That dire warning came from Peter Vincent Pry, a member of the Congressional EMP Commission and executive director of the Task Force on National and Homeland Security.
He testified in front of the House Homeland Security Committee's Subcommittee on Cybersecurity, Infrastructure Protection and Security Technologies that an electromagnetic pulse (EMP) event could wipe out 90% of America's population.
 
... As we reported early last year, Pry, a former CIA nuclear weapons analyst, believes that North Korea's recent seemingly low-yield nuclear tests and launch of a low-orbit satellite may in fact be preparations for a future electromagnetic pulse attack. 
A copy of a report prepared by the Department of Homeland Security for the Defense Department, obtained by Pry from sources within DHS, finds North Korea could use its Unha-3 space launch vehicle to deliver a nuclear warhead as a satellite over the South Pole to attack America from the south. 
As the Heritage Foundation has reported, an EMP attack with a warhead detonated 25 to 300 miles above the U.S. mainland "would fundamentally change the world:" 
"Airplanes would fall from the sky; most cars would be inoperable; electrical devices would fail. Water, sewer and electrical networks would fail simultaneously. Systems of banking, energy, transportation, food production and delivery, water, emergency services and even cyberspace would collapse."
Two points here. First is that the lower the yield of the device, the lower altitude it must be detonated at to produce the desired effect, and, therefore, the more limited the range. Second, with its back against the wall, North Korea cannot be expected to act rationally.
