The most recent edition of al-Qaeda’s magazine Inspire for Spring 2014 contains one of the most troublesome articles I’ve ever read. Issue 12, entitled “Shattered: Story About Change,” initially seemed like most other editions of Inspire that I’ve read in the past, until I came to the last story in the magazine. As I began to read, I felt an eerie sense of evil mixed with technology filling the room.

The final story caught my attention when I read the following, “The open source jihad is America’s worst nightmare… It allows Muslims to train at home instead of risking a dangerous travel abroad.” We’ve all read about the “Lone Wolf” threat and even experienced it as seen in the Boston Bombings. However, what I’m about to tell you, if the terrorists manage to pull it off, will make the Boston Bombings look like child’s play in comparison.

The article in question claimed that open source jihad is a “resource manual for those that loathe the tyrants,” promising information on bomb-making techniques, tradecraft, guerilla tactics, weapons training and more. Curious to see just how effective this open source jihad really was, I turned the page and realized this problem had just become even more serious than before.

The first section of the article was aptly named “OSJ Bomb School” and provided step-by-step instructions on how to make a car bomb “…even in countries with tight security and surveillance.” The explanation was simple, the individual parts and pieces don’t raise concern when purchased or acquired but, when assembled they can create a devastating explosive device. The list of items that are said not to raise suspicion when bought individually include: epoxy, Christmas lights, barometers, gas grill propane tanks, and oxygen cylinders.

The author, using the pen name AQ Chef, doesn’t miss a beat before beginning his step-by-step instructions on how to assemble and test the car bomb, by saying:

“My Muslim brother, before you start reading the instructions, remember that this type of operation if prepared well and an appropiate (sic) target is chosen and Allah decrees success for you, history will never forget it. It will be recorded as a crushing defeat on the enemies of Islam.”

He goes on to specifically explain that the type of car bomb he’s teaching his readers to build is not effective against buildings, but is very effective at killing people.

The author then continues giving a basic chemistry class on gas pressure, units of measure, conversion, and how to mix the oxygen with the propane. Images accompany every step of the instructions showing how to glue the valve stem from a tire to the connecting nut to be used in a subsequent step. The final piece of advice is to load up the bomb with up to 100,000 pieces of shrapnel, using nuts, bolts, and nails to achieve “maximum carnage.”
