Hardening the US against an EMP attack

The Executive Order on Coordinating National Resilience to Electromagnetic Pulses, issued on Tuesday, is a step in the right direction:

Section 1. Purpose. An electromagnetic pulse (EMP) has the potential to disrupt, degrade, and damage technology and critical infrastructure systems. Human-made or naturally occurring EMPs can affect large geographic areas, disrupting elements critical to the Nation’s security and economic prosperity, and could adversely affect global commerce and stability. The Federal Government must foster sustainable, efficient, and cost-effective approaches to improving the Nation’s resilience to the effects of EMPs.

This is a genuine threat. EMPs are not science fiction. The Soviet Union kept a reserve of steam-powered trains in case an EMP from a nuclear blast wiped out their electrical systems.

I wrote about EMPs in the context of North Korea back in 2017:

The North said in its statement Sunday that its H-bomb “is a multi-functional thermonuclear nuke with great destructive power which can be detonated even at high altitudes for super-powerful EMP (electromagnetic pulse) attack according to strategic goals.”
