Well, i had to say something.
I think you're seeing Israel as a country who can only attack and cannot defend it self.
Well, you have a big mistake down there.
So, lets say, Iran nukes israel, the missle will be shut down by an arrow before he get to Jordan, won't success? another one.
since 1994 all Arrow's tests was 100% success, he can take a nuclear warhead.
Iran wont hit israel with a nuke, she can only try, and after the first try, there is no more Iran to launch those warheads.
Evreything that Highsea mentiouned is completley right.
Comon, Iran might have some troops, but we are tlaking about freaking USA here.
Iran HAS NO Migs 29, or any kind of SU's in her AF.
Iran had Migs, but after the war with Iraq they all gone down.
You can look here

about evreything Iran has.
and last thing.
If iran gets to Israel she wont be able to shut down all her sources in 1 bomb, no in 2, and not in 3.
Israel air bases are dispersed in all over the country, in each base there's few models of aircraft, especially in the bases who close to the bounds.
In time of war, like in 2003 when USA attacked Iraq, israeli attack aircrafts and helicopters was up in the air for 24\7 and all missles and the crows was in alert.
At 2003, we knew that Iraq doesn't have with what to attack us, but we were in " code red " so if the war with Iran start, i don't want to think what will be going on over here.
