For whatever it may be worth, I'll tell you why I think the Iranians either developed those plans for the deep testing shaft, (or have actually begun construction), it is to lull the West into complacency (just like the chowderheads at Langley who proclaim Iran is a decade away from a nuke), knowing that at some point there may be intelligence leaks within their own nuke weapon programs, and this shaft is the upstart-nuclear equivalent of a Potemkin village, to give the world the mistaken notion that Tehran is nowhere near the point where they could actually explode a nuke, as they are still seen as preparing the facilities needed to test a device (all the while they are further along than anyone dares suspect).
Personally, if they are able to assemble a missile, mount a warhead (untested or not) on that missile, they will fire it at Israel at their earliest opportunity. If it explodes, they go into a jihadist-mass-orgasm, if it happens to be a dud, they claim it was just a satellite launch that went awry and express "regrets" for any misunderstanding.
OK Mr. Smart guy!
If you think for one moment that we are going to let someone as smart as you fade back into the wood work and not comment ever again,you are dead wrong.
Against a backdrop of imbeciles.lurkers,flammers,teenage zit kings,and assorted miscreants, your stuff sounds mighty authoritative and we want to hear more from you.
That's and order.
And when Isreal retrieves the dud warhead they'll return it with 100 others that won't be duds.
