“Several potential adversaries have the capability to attack the United States with a high-altitude nuclear weapon-generated electromagnetic pulse, and others appear to be pursuing efforts to obtain that capability,” said Graham. “A determined adversary can achieve an EMP attack capability without having a high level of sophistication. For example, an adversary would not have to have long-range ballistic missiles to conduct an EMP attack against the United States. Such an attack could be launched from a freighter off the U.S. coast using a short- or medium-range missile to loft a nuclear warhead to high altitude. Terrorists sponsored by a rogue state could attempt to execute such an attack without revealing the identity of the perpetrators. Iran, the world’s leading sponsor of international terrorism, has practiced launching a mobile ballistic missile from a vessel in the Caspian Sea. Iran has also tested high-altitude explosions of the Shahab-III, a test mode consistent with EMP attack, and described the tests as successful. Iranian military writings explicitly discuss a nuclear EMP attack that would gravely harm the United States. While the commission does not know the intention of Iran in conducting these activities, we are disturbed by the capability that emerges when we connect the dots.”
