The USA and Russia have tested EMP weapons, perhaps we should ask them if the weapon is a serious threat to a large part of the country.
Admittedly, I am not well versed on EMP attack consequences, but while I understand the theory, I still don’t see how a single attack could disrupt every square mile of the U.S. It would seem that many such devices would have to be detonated.

Tested, but neither have them in inventory. Seems to say they weren’t effective enough to keep on hand.
