The threat of an EMP attack is great: enormous destruction, but very low probability. However, as the price of nuclear weapons falls, the threat increases.
Ah EMP attack would cripple electrical power. A complete attack: across the nation, missiles 45 miles above the earth, could wipe out at least a third of America’s population. It would cause total economic collapse.
This threat is being used to promote a pre-emptive military strike on Iran, which has no nuclear weapons.
This video report says that the power grid could be “hardened” — shielded — from EMP attack for $1 billion. Congress does nothing.
If it’s not worth shielding the grid for $1 billion, then it’s not worth war with Iran. It’s not worth having America conduct its own “Pearl Harbor” sneak attack.
