The US government has released hundreds of documents recovered from the compound in which Osama bin Laden was killed. Here is what it learned from them:There was an application form for jihadWould-be jihadists were asked to fill out what at first appears to be a fairly standard application form, including prior experience and goals for the future. But on this form the applicants must decide whether they "wish to execute a suicide operation".Instead of an emergency contact, they are asked who should be reached "in case you become a martyr". Other questions include "have you received military training" and "do you have any chronic or hereditary diseases".Bin Laden was grooming his son as heir to the al-Qaeda empireBin Laden's correspondence includes letters exchanged with a 22-year-old aspiring jihadist - his favourite son, Hamza. The letters indicate that Bin Laden was grooming him as his successor.A letter from Hamza's mother includes a prayer that he follow in "his father's footsteps".He had been reading about English bishopsThe list of Bin Laden's documents contains a curious entry: "Profiles of bishops in the Church of England". It is unclear precisely what information it contains, and why Bin Laden would have been interested.He gave his wife permission to remarryThe following is excerpted from a letter written by Bin Laden to one of his wives: "As for you, you are the apple of my eye, and the most precious thing that I have in this world. If you want to marry after me, I have no objection, but I really want for you to be my wife in paradise, and the woman, if she marries two men, is given a choice on Judgment Day to be with one of them."He had a taste for conspiracy theoryThough much of his reading material was quite sober and academic, Bin Laden had the book Bloodlines of the Illuminati by Fritz Springmeier, an American conspiracy theorist and convicted felon who has argued that Satanic forces have aligned with global elites to create a new world order.Also on his bookshelf was The Secrets of the Federal Reserve by Eustace Mullins, another American conspiracy theorist. Mullins was a white supremacist and Holocaust denier.Bin Laden also had a keen interest in conspiracy theories about 9/11, the mass terrorist attack for which he, himself, claimed responsibility. He had a copy of New Pearl Harbor: Disturbing Questions about the Bush Administration and 9/11 by David Ray Griffin.He was focused on FranceThere were 19 documents about France in his possession.His chief objective was to kill AmericansIn a letter to an al-Qaeda commander, Bin Laden urged his fighters not to become "distracted" by battling local security forces but to instead focus on "breaking the power of our main enemy".His letters make it quite clear that that enemy is the US, and that al-Qaeda's primary objective is to kill as many Americans as possible.He suggests that al-Qaeda affiliates plan attacks on US embassies in the region.He was paranoid about being "bugged"One particular concern was that a Western spy might insert a microscopic recording device into his wife's clothing while she was living in Iran.In one letter Bin Laden writes: "Before um Hamza arrives here, it is necessary for her to leave everything behind, including clothes, books, everything she had in Iran. Everything a needle might possibly penetrate."He called George Bush "this age's Pharaoh"In a letter to the mujahideen, Bin Laden refers to Bush as "a liar, a butcher, and a killer" and "this age's Pharaoh".He said when Bush declared "mission accomplished", he underestimated the "lions of the desert" who would rise up to oppose him.Bin Laden also predicted that the "War on Terror" would be a disaster for the US economy.His pornography collection remains classifiedA spokesman for the Director of National Intelligence told The Telegraph that the details of Bin Laden's stash of pornography would not be released.Reuters reported days after the 2011 raid that the pornography "consists of modern, electronically recorded video and is fairly extensive".But Brian Hale, the spokesman, confirmed that the pornography is not going to be released, nor will the US put out a list of what was found."We have no plans to release that at this point in time."Due to the nature of the content the decision was made not to release it."..
