So do you still think they are still hoping the Iranians are going to pop it in the mail?
At least the Chinese eventually returned the US EP-3E aircraft that landed at Hainan Island. The Chinese very kindly flat packed this aircraft and put all the parts into numerous Airfix boxes. These boxes were then handed over to the Russians who then subsequently gave it back to its rightful owners.

Is it possible that the innards of this drone have now also been flat packed and being returned to the USA via Iran School of Stealth Technology, China, Russia and anyone else willing to pay for the privilege of handling this imitation state of the art UAV that was deliberately deposited into the centre of Azadi Square.
Mr Google
No doubt neither the Chinese nor the Russians will peek at the contents of those boxes.
