US Would Be Wise To Prepare For EMP Attacks On Its Cities
Imagine that a hostile nation - say, North Korea - fires a nuclear-tipped missile at the United States. The missile detonates in the upper atmosphere above a major American city such as Los Angeles, releasing a cascade of charged electrons that damages and destroys all technology and electrical systems within line-of-sight of the explosion. Vital infrastructure on the country's Western seaboard is incapacitated. Large swathes of California and parts of Nevada lose power. Stores, social services and emergency functions that rely on electricity begin to break down, as disorder spreads and the death toll climbs.
