In Homeland Security notes that EMPs “are not a new concern” – just one so menacing that it’s hard to know how to begin describing one that could either occur naturally or be inflicted on us by a hostile power.
“An EMP,” the blog explains, “is an intense surge of energy that interrupts, damages, or destroys all electronic devices on and above our planet. There are natural and manmade EMPs, but each type poses a huge threat to America’s national security and way of life. There is a real possibility of deaths on a scale rarely observed in human history.”
The post provides more background on the EMP concern, but it’s good to know that we’re taken it seriously via the Trump order, which puts the White House in charge of EMP preparedness rather than the Department of Energy or the Department of Homeland Security, “which have a long history of playing down the seriousness of the EMP threat.”
