To further elaborate on Mateo's comment, the Carlyle Group is a highly successful investment company that is not only very involved with the Saudis but also run by alot of bigwigs with ties to the US government, specifically the Bush 41 administration. They quietly facilitate alot of global business deals that would otherwise be potentially perceived as distasteful by the American public. I'd guess that a desk is being set up there for Mr. Rumsfeld as I type this.
