"Senior CIA officers targeted Petraeus because they didn’t like the way he was running the agency – focusing more on paramilitary operations than intelligence analysis. They used their political clout and their connections to force an FBI investigation of his affair with Paul Broadwell and make it public. 'It was basically a palace coupe to get Petraeus out of there.' Petraeus also was betrayed by his bodyguards, who leaked in affair with Paula Broadwell to his enemies in the agency.
The book claims that neither Stevens nor even Petraeus knew about the raids by American special operations troops, which had ‘kicked a hornet’s nest’ among the heavily-armed fighters after the overthrow of Libyan dictator Muammar Gaddafi.
John Brennan, President Barack Obama’s Deputy National Security Adviser, had been authorizing ‘unilateral operations in North Africa outside of the traditional command structure,’ according to the e-book. Brennan is Obama’s pick to replace Petraeus as head of the CIA."
