Khan's blog (hosted at revolution.muslimpad.com) is believed to be the inspiration for Revolution Muslim, a radical spinoff from ITS that spawned some of the biggest American jihadi characters of the past three years, most notably Zachary Chesser. Now in prison, Chesser's rise to prominence was capped by the threatening of the creators of South Park in April 2010 over a story line involving the depiction of the Prophet Mohammed.
In 2004, Khan moved with his parents to Charlotte, North Carolina, where he continued his online exploits in his parent's basement. As the Iraq war was increasing getting more violent, Khan's postings became more extreme as he posted content from al Qaeda's affiliate in Iraq. At one point, his parents were so concerned about his obsessive use of the Internet that they sometimes unplugged it.
Prior to his departure to Yemen, in early 2009, Khan started his foray into larger publishing and independently released, edited, and wrote for a new online jihadi magazine titled Jihad Recollections. Although it only lasted four issues, it was a precursor to the more popular Inspire magazine that he helped edit with Awlaki. It also helped lower the bar for aspiring jihadists, especially for native English-language speakers. For instance, Mohamed Osman Mohamud, who was arrested in November 2010 for the Portland Christmas-tree-lighting plot, wrote an article for Jihad Recollections -- as did Jesse Morton, a co-founder of Revolution Muslim. Mohamud later submitted an article to Inspire.
Khan moved to Yemen in October 2009. It's still unclear whether it was because he had been tapped by Awlaki to come over, but it's likely he was feeling the heat from U.S. counterterrorism officials -- many of his online friends had, by this time, been arrested. Once in Yemen, Khan helped edit and write articles for Inspire magazine, which has released seven issues since June 2010, the latest earlier this week. Many experts see the most recent issue as a bit of a dud due to the lack of content compared with the previous six issues. But, in retrospect, it is probably a bit thin because Khan and others were on the run from U.S drones.
Khan's provocative style in Inspire caught the attention of the media, though, with titles such as "How to Make a Bomb in the Kitchen of Your Mom," "The Ultimate Mowing Machine," and "I Am Proud to Be a Traitor to America." Indeed, Inspire even lived up to its name, having been found in the apartments and computers of some American jihadi plotters over the past year. An Inspire article was also used as a bomb-building guide by Naser Abdo, who failed in an attempt at a second Fort Hood attack.
Khan was also active on Facebook under his alias Abu Risaas. Although his account is no longer active, following his departure for Yemen in 2009, according to Aaron Weisburd who actively collects data on online usage by jihadists, Khan had 39 Facebook friends and 18,800 friends of friends -- showing the strength of his community. Simply put, Khan was the node, connecting various networks within the online jihadi community.
Although Khan was never in the same league as Awlaki in terms of religious stature and oratory skills, Khan made up for it in his ability to connect disparate groups online and facilitate information not necessarily readily available in English. For thousands of would-be radicals, he made the jihadi cause accessible. As such, if Khan indeed is dead, he will go down as one of the most important pioneers and influential figures in the history of the American jihadi movement.
