B-1B Aircrews Preparing for Return to the Middle East

Since when were B-1bs "non-nuclear capable" aircraft?
That was an odd nugget in the story.

LTC Ivan Raiklin, Esq. Remember a Layover at Sheppard and watching the Plane Capt put one thru its preflight. making sure that all the control surfaces moved correctly not special until I saw the Tail, the Ass of this Big Bird move. Never seen the whole tail of a Plane move before.
