As I didn't quote or attribute that remark to anyone or anywhere, the most reasonable assumption would be, its mine.

Well, when the last Iranian aircraft crashed a bit back, the BBC immediately trumpeted that the general non-airworthiness of the Iranian air fleet was due to the American Embargo on aircraft parts(ARF!! never mind that the aircraft was a Tupolev!). So, I'd reckon that the waiving of the U.S. embargo specifically for aircraft parts was purely a P.R. gimmick to show that the U.S. be the good guys in this case.. People's safety over politics??
