While no one can argue that the threat of a nuclear bomb obliterating a city (or country) is devastating, the threat of an electromagnetic pulse (EMP) attack may be similarly harmful and incredibly destructive, according to some experts.
An EMP occurs when a nuclear device is detonated just above the atmosphere, causing enough radiation to create a very powerful electromagnetic field capable of frying the electric grid and most electrical devices in the vicinity.

It would be like blowing a fuse on a national scale, with industry, economy and emergency services completely crippled within a matter of seconds.
Data centers, power plants, telecommunication networks and almost anything we have come to rely on would likely collapse from the effects of an EMP blast, and yet, so far, most governments are doing very little about protecting against such an attack, even as the likelihood increases.
In 2000, Congress established a commission to assess the threat to the United States of an EMP attack and four years later, the committee presented a 70-page summary of the threat, with a final report issued in 2008.
According to that report, “several potential adversaries have or can acquire the capability to attack the United States with a high-altitude nuclear weapon-generated electromagnetic pulse (EMP). A determined adversary can achieve an EMP attack capability without having a high level of sophistication.”
The report went on to say that EMP was one of just a handful of threats that with “catastrophic consequences” for society, which could cover a wide geographic region within line of sight to the nuclear weapon.
“It has the capability to produce significant damage to critical infrastructures and thus to the very fabric of US society, as well as to the ability of the United States and Western nations to project influence and military power,” it read.
In congressional testimony, NASA Deputy Administrator and former science advisor to the President, Dr. William R. Graham, added that “… the degradation of infrastructure could have irreversible effects on the country’s ability to support its population.”
So, what’s the price for a little protection? According to Electric Infrastructure Security
(EIS) Council chairman and CEO Avi Schnurr, only about $1 billion.
Indeed, speaking to the Times of Israel
recently, Schnurr called the solution “extremely affordable.”
The EIS works with both governments and power providers to try and coordinate international efforts on electric infrastructure protection. Not just against terrorism, either. Solar flares can easily cause enough geomagnetic disturbance to cause a similar effect. The last recorded incident happened 150 years ago, observed by British solar astronomer Richard Carrington, and many scientists believe the chances of getting through another 30 years without severe solar flares are just 50 percent.
To protect against the grid getting fried, countries would need to harden electrical infrastructure with things like geomagnetically induced current blockers, which cost little but are not yet mandated by the government.
So here’s a thought; instead of spending billions making and stockpiling weaponry, why do governments not spend a fraction of that amount to defensively protect their most important resource –electricity—from disaster?
