Prediction: there will be no Iranian/US agreement, today. Just another failed deadline (there have two previous deadlines) ala Obama's "red line" in Syria.

And when the "agreement" is reached,  it will not be in writing;  Kerry will insist that it is not a binding treaty (he has already made that rather stupid admission).  More than this,   Kerry has been instructed by Obama to allow Iran to store it's nuclear material in underground bunkers,  preventing their destruction by either Israel or the other Arab nations in the region (none of them support this "peace" effort).  And, in June,  if not another failed deadline,  this Administration will boast about the "peace accord" with the same feckless ineptness that went into its brag about Yemen and Somalia and the "death of al Qaeda" and the J.V. status of ISIS and the declaration that Iraq was "strong,  stable and sovereign."
