There is a wide range of opinion on the potential implications of Electromagnetic Pulse (EMP)–either that generated by a terrorist nuke ground burst, or a nation-state’s high altitude air burst(s). I’m convinced that the threat is real. But don’t just take my word on it. Back in 2004, the U.S. Congress commissioned a study by a prestigious panel of scientists to investigate the potential implications of EMP. I suggest that you take time to read the Heritage Foundation’s summary, which followed the release of the EMP’s Commission’s report. (see: http://www.heritage.org/Research/NationalSecurity/bg1784.cfm). And if you feel so inclined, go on to read the EMP Commission’s report–most of it is written in layman’s terms. The text of the report can be found here: http://www.globalsecurity.org/wmd/library/congress/2004_r/04-07-22emp.pdf. Warning: Reading this report has been known to cause rational people to buy large food storage supplies and a spare 4WD vehicle with a pre-electronic ignition system.
