It's pretty clear to me (and most rational people) why the events in Benghazi occurred. The Obama administration did not want to provide the consulate and ambassador Stevens with the proper security , because they wanted to avoid a scenario where Muslims could possibly be harmed by Americans. That's why there were no armed guards at the compound, despite threats to the ambassador's life in the weeks leading up to the attack.
Obama is more concerned with being conciliatory to Muslims than he is with actually protecting Americans. If more Americans die, then that's just the price we pay for peace with the Islamic world. As far as he is concerned, these are just "bumps in the road" anyway. It's disgusting!!
