Staging Nukes for Iran?

Why the hubbub over a B-52 taking off from a B-52 base in Minot, North Dakota and subsequently landing at a B-52 base in Barksdale, Louisiana?

(...)

So I called a old friend and retired B-52 pilot and asked him. What he told me offers one compelling case of circumstantial evidence. My buddy, let’s call him Jack D. Ripper, reminded me that the only times you put weapons on a plane is when they are on alert or if you are tasked to move the weapons to a specific site.
Then he told me something I had not heard before.
Barksdale Air Force Base is being used as a jumping off point for Middle East operations. Gee, why would we want cruise missile nukes at Barksdale Air Force Base. Can’t imagine we would need to use them in Iraq. Why would we want to preposition nuclear weapons at a base conducting Middle East operations?
His final point was to observe that someone on the inside obviously leaked the info that the planes were carrying nukes. A B-52 landing at Barksdale is a non-event. A B-52 landing with nukes. That is something else."
