  The chances of an EMP attack
  Q: I’ve heard a lot from you about how dangerous an EMP attack could be. But how likely is it that anyone will actually try to attack us with an EMP?
  A: Unlike the EMP Commission, most national security experts view EMP attacks as a second rate threat. While perhaps some small terrorist groups or rogue nations might launch a localized EMP attack that might take out a substation or two, it’s unlikely that any country capable of launching a major EMP attack would actually do so.
  Q: Why not?
  A: Because to launch a major EMP attack, a country would need a large nuclear weapon. And if a country was planning on using a large nuclear weapon, it would make more sense — in the morbid logic of war — to conventionally drop it on a city than to launch an EMP attack which would at most cause some brief power disruptions in a few states. As physicist Yousaf Butt put it, “A weapon of mass destruction is preferable to a weapon of mass disruption”.
