Gadaffi had/did all the things the Saudis do, but he suffered mass protests and ultimately full revolt [i]before[/i[ NATO intervention, so did Saddam. Take another look at Saudi Arabia, yes it's oppressive but in the majority of the country the royal family is quite popular. The clue is in the name, the country only exists, and is a regional power, because of the House of Saud.
Bahrain is more complicated, but if you look at the medium term and the short term prior to the protests this spring you will again see a generally upwarded trajectory, and (again) the ruling family is deeply embedded in the identity of the country.
