An electromagnetic pulse (EMP) attack could be triggered by a nuclear warhead detonated at high altitude over the United States. The resulting blast would create an EMP, a shockwave that could "cripple military and civilian communications, power, transportation, water, food, and other infrastructure" and lead to the deaths of millions of Americans.

This threat emanates most notably from Iran, whose president has promised that "a world without America" is possible and attainable. The Iranian regime is building up its ballistic missile and nuclear capabilities and has tested high altitude missile detonations.

Our country is unprepared to deal with an EMP attack. Here's what you can do:
