Because it makes sense to remove the nuclear refining plant deep underground.  Left where it is, as it is, it is a continual danger regarding making weapons grade material.

come on this has got to be some sort of a joke question. Do they have the news on your planet?

TORATORATORA, you've been telt multiple times to refer to DDIL by that name so I suggest you do that or more posts will be deleted. 

Because he is a sandwich short of a picnic!

Because they need a MOP to penetrate the ground to the enrichment site and only USA have them. Do pay attention. 

DDIL -I don't even watch the news anymore.

If the worst is going to happen I'd rather not know.

DDIL - I get a copy of the Daily Mail sent from Borrowbox (my library online books and newspapers)- free of charge.

I skirt over the headlines unless something catches my eye and then to the finance or health page on the relevant days, then the cartoons, letters page and sport. 

TTT, you are trolling DDIL.  There is no other word for it.  You've just returned from suspension but if a longer rest suits you better carry on.

I gave an accurate answer at 19:08

It's not rocket science (no pun intended)

Only the USA has the bunker busting bombs needed to take out the Fordow uranium enrichment facility which is buried underground.

Iran was weeks away from building a nuclear bomb before this kicked off.

So either America to do it or they lend Israel a stealth bomber equipped with the bombs.

19:22 yes what I said at 19:08

It'll be a whole lot worse if Iran build a nuke.

It's to stop the mad mullahs getting nukes. What do you think they'll do as soon as they get one? 

There will be no problem if he goes ahead, he'll just deny involvement even if hes's seen on a live feed giving the go ahead himself.

He might do his demented dad dance on the day of action then attempt a serious, statesman-like face as he asks who could have dropped such a bigly beautiful bomb.

He's a shaved ape with no sense of right or wrong and the world will be a better place when he's gone.
