It's obviously a fake.
However the Iranians aren't stupid enough to believe that they're fooling anyone. They ar simply trying to pull attention away from what they are actually doing which is building a nuclear bomb.
They will likely have a functioning nuclear device to test by the end of this year and that's the real threat. As far as delivery it will probably be a suitcase device to smuggle into wherever they decide they want it and who they want to hold hostage.
So far no one has shown any real effort to stop them.
This ruse with the fake fighter is just to buy time (I would think mostly with their own people) like all the other hand waving and blustering they've done is.
Our administration intends to talk with them now...that will buy some more time.
So who are the stupid people here??
