I guess The One figures he'd be safe in the White House bunker, since any Iranian ICBM is going to not have that high yield of a warhead, and likely not be all that accurate. Or that he could helicopter out in Marine One to that "undisclosed location" before the imcoming landed.
Of course his constitutents in DC would be SOL.
Not to worry Hussein will be in a safe warm place playing gulf... far from the madding crowd in DC.
