It is entirely believable -- and even sensible, from the Saudis' point of view, that if we leave Iraq, they and other Sunni states will interfere in various ways to protect their sectarian cousins.

Snow is an idiot just for seriously thinking that a slow third-grader couldn't parse his mealy-mouthed non-response.
In completely unrelated news, gasoline prices jumped 10¢ overnight here in California.
