"they may not want to provide access to all the evidence against Saddam to Iranian prosecutors"
That's a good point. And yes, there are probably other reasons we won't know about, why the Iraqis decided not to include crimes against Iran.
"Rafsanjani...: confuse, divide and conquer"
You're right again. Thanks for the reminder.
You have a point. I hope that they include that Saddam used chemical warfare against Iran as well as his own population.
