U.S. get close to Iranian nuclear sites
The recent blast in Bushehr province close by Bushehr nuclear facility on February 16 was apparently the Iranian air defense in use. The pilotless U.S. jets started spying of late on nuclear sites in Busher and other Iranian provinces where the U.S. suspect nuclear weapon can be developed. Until recently, the pilotless jets were only reconnoitering the territory but now the U.S. are on the go to start using pilotless scout-attack jets capable to carry bombs and missiles (with nuclear charge as well). Iran reported it was exactly that type of pilotless jets they splashed over Busher nuclear site as the U.S. were testing it in Iranian air space.

I think your talking about drones not jets. I dont think the US has any pilotless jets.

I doubt the US will attack Iran bogged down in Iraq.
