Yes, Hilary Clinton is likely at fault to a degree when it comes to what happened in Benghazi. The many investigations and reports, as well as her own admissions seem to indicated that some mistakes were made by her State Department as well as other groups and individuals. In the end, however, the responsibility for what happened in Benghazi lies with the individuals who participated in the attack.
Hillary Clinton is to blame for what happened in Benghazi; however, not for the reasons that many of her political opponents cite. Clinton was an advocate of U.S. intervention into Libya. As a result of overthrowing the Libyan government and not having a plan to secure the country afterwards, the situation in the county became very dangerous. The Benghazi attack was a result of a lack of security on the ground after Clinton had supported overthrowing the government.
I can't believe that Hilary Clinton continues to have this thrown at her. Funny how no one ask if George W. Bush and his cabinet were responsible for 9-11. No for some odd reason he is hailed as a hero for a situation that was even worse than Benghazi yet Hilary Clinton along with the Obama administration continue to be under scrutiny for Benghazi, something that was another terrorist attack and they had no idea was going to happen.
Hilary Clinton is not to blame for what happened in Benghazi. She was a part of a team great larger that herself when those issues where dealt with. People choose to blame her because she is in the public eye. If there is anyone to blame it should be everyone not one single individual.
