Except for a terror attack against the USA. Until they actively AND PUBLICLY denounce terrorism, ANY Saudi is a potential terrorist or terrorism sponsor. After the next attack they will be killed on site. Mark my words.
Oh, but they do actively AND PUBLICLY denounce terrorism.
Thing is, though, that to them "terrorism" means any activity to topple the Gang of Saud. Oh, and also any moves by Zionists and infidels to protect themselves against Wahabi depredations.
