It seems that HIllary thinks either the possibility exists or that she needs to appear strong in support of using the threat of retaliation to ward off such an occurrence:

QUESTION: …Does massive retaliation mean you would go into Iran, you would bomb Iran? Is that what that’s supposed to suggest?

CLINTON: Well, the question was, if Iran were to launch a nuclear attack on Israel, what would our response be. And I want the Iranians to know that if I’m the president, we will attack Iran. And I want them to understand that, because it does mean that they have to look very carefully at their society, because at whatever stage of development they might be in their nuclear weapons program, in the next 10 years during which they might foolishly consider launching an attack on Israel we would be able to totally obliterate them. That’s a terrible thing to say, but those people who run Iran need to understand that, because that perhaps will deter them from doing something that would be reckless, foolish and tragic.

Sometimes the posturing that is done amazes me.




>>>>You're kidding right? The evidence is everywhere in the news and on the web. You have only to do a little research.

>>>So you are telling me that Iran is preparing major attack on Israel, and that evidence is in media ??

>>hmmm... seriously, what preparation do you need to fire off a nuclear missile, once they have one? Just push the button... right?

>Once they have one. Right now they don't and there is years ahead before
>they can come even close to having missiles. In the meanwhile Israel already have considerable arsenal, while also having one of most advanced armies on planet. I read somewhere predictions that Israel could be able to neutralise Iran in case of military conflict within 72 hours!

>They (Iran) have 0% chance of winning conflict with Israel (backed by US) and they know it. I would rather consider harsh rethorics by Ahmadinejad as act of fear and to some extent anger with present situation where they are really hopeless against direct threat that they are facing.

>They could be angry, but they are not fanatics to the extent of wanting
>to commit collective suicide by attacking Israel. Imo, Even if Israel do 'preemtive strike', Iran will still avoid to seriosely retaliate even if they had nukes, because on the end that would mean total dissaster and possible extinction for them.
>Back in cold war days, they had whole computer simulations of possible nuclear conflict; do you think that they dont have anyone with half brain to do simple math. (10 missiles < 5000 Missiles )

>If you were Ahmadinejad having your first 10 'homebrew' nukes would you still pool that trigger ?
