The Times notes that Iran appears to be "beefing up its air defenses" recently in response, and has been buying Russian radar systems and surface-to-air missiles to better protect its nuclear facilities.
Agence France-Presse writes that an Israeli Air Force spokesman neither confirmed nor denied the exercise's existence or its focus on Iran, saying only that "The Israeli Air Force regularly trains for various missions in order to confront and meet the challenges posed by the threats." AFP notes, however, that the same week that the exercise took place, Israeli Deputy Prime Minister Shaul Mofaz told the Yediot Aharonot newspaper that "If Iran continues its nuclear weapons program, we will attack it."
