I doubt that Iran has been exported nuclear know how by Saddaam - I believe that Iraq fought a prolonged war against Iran. They did not like each other. Most likely Iran's nuclear program is by their own engineering, or perhaps with the help of Pakistan. Please do research before spreading innuendo.
Apparently you attack first and don't do any research yourself. You ignore the fact that Saddam sent his AirForce to Iran, his mortal enemy, during the first Gulf War. You also appear to be ignorant of the U.S. Congressional Hearings where Iraqi sources were cited as having transferred 5-6 six months before we invaded, "hundreds" of "washing-machine-sized" centrifuges from Iraq's nuclear program to China...loaded with the uranium they were enriching.
If given credence, one has to surmise that Saddam evidently felt it was better to give them to the Mullah's than to have done the nuclear effort all for nothing. They also manifestly had "a deal" before he would dare do such a thing.
