IIRC the estimated values were, excluding sensitive avionics systems, that the export F-35 had frontal RCS just smaller than an F-16's, while the non-export version had all around RSC just smaller than a bumble bee or something along these lines.


As for the drones, the comparison to the Stuxnet thing is a bad one, because publications estimated the virus was inserted physically into the closed network of the facility/facilities in question. The Drones, by definition, receive wireless signals, and there's a buttload of them at any given time all around the Gulf / Iraqi airspace. Any actual breach would have been addressed within hours or days, not seconds or minutes.
It's far, far more likely that the drone simply crashed. Those things happen in peacetime, and Iran (and similar regimes) are far more notorious for propoganda lies than the west is (not that the west is short on liars, but it's less frequent because it's easier to disprove stuff when you don't have a a tight death grip on the media).

That said, your scenario is not impossible - I just personally find it significantly less plausible than mine based on what I know about the militaristic culture of middle eastern states - they will literally twist anything to make themselves appear as heroic as possible, any day of the week. I remember back when Iran had those ballistic missile test runs and only some of the missiles worked, and they went ahead and banged together a bad photoshop job to make themselves appear more badass.
Their photoshop skills were terrible and make me doubt, probably unfairly, anything else they can do with a computer:

We're all hard wired to be in cognitive disonance about some things regardless, so you're not free from that yourself. Who's to tell who has it more on this case?

Pretty much agree with ya on the rest of your post.
