Thanks, I was not aware of that involvement by Iran.
Reports at the time, since erased or buried in a tumult of other articles, said the Kuala Lumpur, Malaysia meeting at which the USS Cole plot was planned [and the failed USS The Sullivans plot] and which was attended by two of the 9/11 hijacking pilots who had been driven there by an Iraqi who was later found with contact info for the people involved in the 1993 WTC bombing, etc., was held at the residence of an Iranian diplomat.
It was never mentioned again.
Around the same time, Iranian diplomats in NY were caught photographing sites there. That report was buried. [Iraqi diplomats were also caught.]
