From Carolina Journal Radio Program No. 693: It’s unlikely that you’ve heard much about the potential threat of an electromagnetic pulse, or EMP. But James Carafano hopes to raise awareness of the devastation that could result in the United States from an EMP attack. Carafano, vice president for foreign and defense policy studies at the Heritage Foundation, says the complications from an EMP attack could end up killing nine out of 10 Americans. He’s urging policymakers to take steps that would limit the potential for such havoc.
