From Fox News, a rushed together video package of POTUS surprise dash into Baghdad. The fresh contribution here is the POTUS's choice of metaphors, in response to a pat question at a so-called student townhall meeting in Turkey, for why he has not yet transformed the American military policy -- that is, why are the American imperialists still in Baghdad?  POTUS replies that America is slow to turn around because it is "like an oil tanker...not a speedboat."   More ringing images such as this -- America is like an armored Cadillac limo not a flimsy Toyota Prius -- and we can relax our fretting that the Obama administration is anything other than a bootless caretaker apparatus waiting for re-election.  The correct metaphor for the question?  America is the guarantor of liberty and freedom, how're you doing?
