Worse yet, evidence continues to accumulate that both North Korea and Iran are interested in a nuclear weapons application that poses a particular and extraordinary danger to the United States: a ballistic missile-delivered warhead that would cause an electro-magnetic pulse (EMP) capable of inflicting what a blue-ribbon commission recently called "catastrophic" damage to the electric grid and electronic systems across the country.

CENTERFORSECURITYPOLICY: Broken treaty

Their job has been to examine in detail a phenomenon known as electro-magnetic pulse (EMP) that could be used by our enemies like Iran to effect such devastation.

CENTERFORSECURITYPOLICY: EMP and you

It is reckless at a time when countries like North Korea and Iran are acquiring missiles capable of delivering devastating electro-magnetic pulse (EMP) or other nuclear attacks against this country.

CENTERFORSECURITYPOLICY: Get real on nuclear deterrence

Another which has been getting increasing attention could be delivered via the kind of nuclear-armed ballistic missile that Iran and North Korea have been developing: a strategic electro-magnetic pulse (EMP) attack.

CENTERFORSECURITYPOLICY: America's Achilles' Heel

If used to detonate nuclear weapons in space over targeted nations, such missiles could unleash electro-magnetic pulse (EMP) attacks, resulting in widespread destruction of electrical grids and what a congressional commission has described as the "catastrophic" disruption of civilizations reliant upon them.

CENTERFORSECURITYPOLICY: America's commitment to freedom

The state of America's aging nuclear arsenal also troubled Mr. Gaffney, who warned "Our stockpile is not as safe and reliable as we could make it" and that a resumption of nuclear testing is needed to permit such improvements to be made and to diagnose and correct the Nation's yawning vulnerabilities to electro-magnetic pulse (EMP) attacks.

CENTERFORSECURITYPOLICY: DoD Budget Threatens Cuts to Crucial Programs

In a new op-ed in today's Washington TImes, Center President Frank Gaffney argues that we had better be awakened, though, to one other, particularly ominous prospect: Determined terrorists could inflict lasting, if not actually permanent, damage on the United States' electrical and other computer-based systems by employing small nuclear or non-nuclear devices that generate what is known as electro-magnetic pulse (EMP).
