Stop for a moment, and think about what you are doing this very minute......
You obviously are reading this post and possibly looking at other online media while enjoying your iTunes or whatnot. Somewhere off the coast of or in the U.S., some Terrorists or rouge nation have just launched an attack. It comes in the form of single missile tipped with a nuke that detonates in the upper atmosphere. At that moment, your laptop, cell phone, lights and pretty much anything plugged in shuts off and never turns back on. You are just fine, so you wonder what just happened? You also find that your car no longer starts. Something bad HAS happened, and you don't even know. Communication is cut, transportation is cut, and panic soon sets in.
Folks, Electro-Magnetic Pulse or EMP for short, is a real threat to anything with a microchip in it. It's a major security issue and should be handled as such. Most people think that the threat is possible but not likely, so money and time is not invested in retrofitting or "hardening" our infrastructure. Since we are all dependant on technology that we have grown accustomed to, in some cases, not being able to live without should scare us all enough to want to act.
I recommend that you go to your local library and ask for or download to your Sony or Kindle eReader the book titled, "One Second After" by William Forstchen and read it (ISBN-10:0-7653-1758-3). I couldn't put it down because it really made be me stop and think about how dependant we as a society are on technology and how easy it can be to become disconnected with everyone around us. This book is a Sci-Fi novel, but the information it is based upon is real. I enjoyed this book because it's the first novel I have read in a while that actually interested me enough to continue to read to the end and even recommend. I hope you find it as good as I did.
