Threat of EMP Attack on US and What to Do About It

"In a recent letter to investors, billionaire hedge-fund manager Paul Singer warned that an electromagnetic pulse, or EMP, is 'the most significant threat' to the US and our allies in the world," write R. James Woolsey and Peter Vincent Pry in the Wall Street Journal.

He's right. Our food and water supplies, communications, banking, hospitals, law enforcement, etc., all depend on the electric grid. Yet until recently little attention has been paid to the ease of generating EMPs by detonating a nuclear weapon in orbit above the U.S., and thus bringing our civilization to a cold, dark halt. ...

The much neglected 2004 and 2008 reports by the congressional EMP Commission—only now garnering increased public attention—warn that "terrorists or state actors that possess relatively unsophisticated missiles armed with nuclear weapons may well calculate that, instead of destroying a city or a military base, they may gain the greatest political-military utility from one or a few such weapons by using them—or threatening their use—in an EMP attack." ...

What would a successful EMP attack look like? The EMP Commission, in 2008, estimated that within 12 months of a nationwide blackout, up to 90% of the U.S. population could possibly perish from starvation, disease and societal breakdown ....

What to do?

Surge arrestors, faraday cages and other devices that prevent EMP from damaging electronics, as well micro-grids that are inherently less susceptible to EMP, have been used by the Defense Department for more than 50 years to protect crucial military installations and strategic forces. These can be adapted to protect civilian infrastructure as well. The cost of protecting the national electric grid, according to a 2008 EMP Commission estimate, would be about $2 billion...

What is lacking in Washington is a sense of urgency. Lawmakers and the administration need to move rapidly to build resilience into our electric grid and defend against an EMP attack that could deliver a devastating blow to the U.S. economy and the American people. Congress should pass and the president should sign into law the Shield Act and CIPA as soon as possible. Literally millions of American lives could depend on it.
