Such BS - our military has been EMP hardened for 40 years. I think we have that figured out by now.
also warns that EMP or geomagnetic disturbances could cause catastrophic damage and the loss of life in the United States.
This much, at least, is true. Society in general is wide open to EMP attack.
Yes but only localized.
The civilian infrastructure is a different story.
I thought the EMP strike would affect American utilities...
