This has been noted in Israel. This is not the first threat of this sort from Iran.
Israel destroyed Saddams Nuclear facility in the 80's and don't be suprised to see them act preemptively to protect their population, again.
Iran has stated they would be happy to exchange Nuclear blasts with Israel. Because, as they see it, the Arab World can survive it, Israel can't.
Will Israel ever knowingly allowing that possibilty to occur?
...just my 2 cents is all
Best possible scenario..the threat of a pre-emptive strike by Israel..coupled with a loud and clear statement buy Israel that IF a nuke is ever detonated in Israel..then Israel will respond against Iranian cities..might be enough to move the Iranians to overthrow the very unpopular mullahs..
FF Israel and the US Navy will have a very effective missle shield .Iran will burn to the groud.
