Re: Russia to sell surface-to-air missiles to Iran
First, what makes you think that Isreal cannot refuel these planes in flight?
Second, the easiest way to approach Iran would be to sling some cruise missles under the wings. The cruise missles could be fired from hundreds of miles away, penetrating the airspace at very low levels, while the fighters return to Isreal.
The Isrealis are capable of thinking out of the box, and they have the technological abilities to adapt the aircraft and weapons already in their arsenal.
