He claimed to be out to tell the truth on the raid that killed Osama bin Laden. But the Navy SEAL who wrote the first hand account of the mission could actually have been motivated by revenge – on his own comrades. A rival book alleges that Matt Bissonnette, who wrote ‘No Easy Day’, had ‘bad blood’ between his former colleagues and commanders because he was kicked out of the unit. ‘No Easy Op’ claims that the soldier was ‘ostracized’ when he inquired about leaving the Navy to start a business and was sent home suddenly before quitting. Feeling scorned Bissonnette could have penned his novel as a way of getting back at the military in which he served for 14 years with distinction. No Easy Day, which is due out tomorrow, is the first account of the bin Laden operation from a member of the squad who was there. But it has proved controversial because Bissonnette, writing under the pseudonym Mark Owen, did not seek approval from the authorities before he wrote it. It also disagrees with the official White House version of events which was put out at the time and has caused the Obama administration consternation.
