If groups adversarial to Obama had seized all the operations in Benghazi, far greater damage to Obama’s foreign relations would have transpired.
Obama believes he controls those who committed the actions and the deaths were simply casualties in the ‘fog of war’.
All of the Libyan groups are adversarial to Obama. Obama may think that he controls the situation but he does not. They hate the US and only want our money. They want us out of their country. That is why Panetta and the others decided to do nothing when the CIA facility was attacked. They didn’t want to further anger the Libyans by responding with force.
