According to this recent blog entry from American Thinker, John Limbert has been named the State Department's chief expert on Iran. And he definitely has expertise - among other things, from his time on the advisory board of the National Iranian American Council (NIAC). NIAC is considered by many to be the de facto Iranian lobby in Washington.
Just think: in his new job, Limbert will get to see all those classified memos, cables and reports that he only heard about before. Plus, he'll be in all discussions of any significance on Iranian policy. At least there won't be any more ambiguity in State's policy on Iran: it'll be consistently pro-Iranian.
