The Kennedy heir is standing up for her family's legacy.
Access Hollywood: Saudis have a long history of committing crimes in the USA, then being whisked bank to the kingdom without facing justice for those crimes. Saudi Arabia is not a friend to the USA; we use them for oil, that oil gives the Saudis the power to manipulate the USA (or more precisely, factions within the USA) to do its bidding. Never forget how the Saudis conspired with members of the Bush Jr. administration to falsely claim that there were valid reasons for war with Iraq. There is insufficient evidence to link the royal family to acts of war against the USA (9-11, embassy bombings, USS Cole etc.) but it is safe to say that these acts of violence are not widely condemned in Saudi Arabia, birthplace of Wahhabism.
