The logistical problems that exist for Israel may be hard to overcome.
1)Geography: The 3 routes to Iran include airspace of; Syria and Iraq, Jordan and Iraq, or Saudi Arabia and Iraq. None have given the go-ahead to Israel, with some outright denying use of their airspace.
2)Equipment: They use F-15, F-15 Strike Eagles, and F-16's. The F-15 would most likely be used due to its longer range, however it still would need refueled at a minimum of twice to complete the mission. Meaning that somewhere over Iraq, a Boieng 707 would need to be flying to do this.
3)Lack of support from the US (and I do believe that Barry would absolutely go to the UN to try to block any action by Israel)

It definately wouldn't be a sneak attack. Iran would have knowledge of an attack 60-90 minutes before it occurred and could mount a counter-attack and anti-aircraft campaign.

I firmly believe that Israel will take covert internal actions rather than an air strike.
