just let the Israelis take out their nuclear reactor like they did with Saddam...
I can guarantee you thats not
Forget the polticial implications it is just not feasible technically.
You are talking about reactors
in plural not just one, unlike the Iraqi reactor. First, you would have to know the exact location of every venue and then taking them all out would require a massive collective airstrike timed to perfection. The Israeli Air Force just doesn't have enough planes to pull something like that off. Add to that refuelling is a problem- they don't have an aircraft carrier docked in the Persian Gulf to refuel they would have to fly back to Israel over hundreds of miles of hostile airspace.
Unless you take out all the reactors in one fell swoop you have actually done nothing since whatever is left can be duplicated- so it is a matter of all or nothing. Either destroy them all or don't bother doing anything.
No, from a techincal/strategic standpoint, if anyone is going to attack Iran it can only be the U.S. with numerous aircraft carriers in the Persian Gulf deploying hundreds of aircraft simultaneously striking all the targets.
