Our intel must see something in the cooker given the additional abm assets forwarded to the region.

Ah, but a “demo” of a nuclear test (that Israel drops a nuke in from their newly-moved ship (which eliminates the Iraq-Jordan overflight issue)) would be hard to distinguish between the Israel strike and the Iran test, wouldn't it? Except the Israel “test” would explode over top the Iranian test lab, not the test site.)
On the other hand, YES - our intel agencies would have the knowledge.
But the White House and Pentagon would (deliberately_) ignore that intelligence anyway. They have been bred to hate Israel even more than they hate the US military and capitalism.
That is why I view the recent deployment of Patriot and SM-2 ships to the region evidence that at least someone may have their head screwed on right and is preparing for backlash of some sort.
