Thanks for legging this one out.  This is a common tactic used against leaders the US does not approve of.  Ahmadenijad, for all his idiotic quotes, didn't say half the stuff people think he did in the US. People widely belive anything via association if it is repeated often enough. Occasionally this works in our favor, such as the "I can see Russia from my house" quote that was a satire by Tina Fey yet is largely associated with Sarah Palin.
