Iran has shown Russia several American drones and spy planes it downed.....

Now this part makes me laugh
a) Washington never confirmed Tehran had shot down any of its drones.
B) Washington has expressed concern about Tehran's possession of the aircraft.
Credit to Iran on this, they went their own way 20 years ago and put their money into developing their own self defence systems...it seems it has paid dividends. They are blowing American aircraft out of the sky at will.
Would be interesting to see if that capability extends to Fa18`s or above.
If there is a lesson to be learned from Iran...its that developing your own systems is the way to go.
