I believe that we had glimpses of this army being formed in Benghazi. They were to defeat Assad in Syria but cannot do so, and now they are on to their auxilliary target, and I do believe Obama is behind supplying ISIS and giving them intel.
Chris Stevens unwittingly gave his life setting it up.
My money is therefore on ISIS as an historical prediction.The Iranians will fight them to the death, just as they have done in Syria.
We've got to learn to supply the means and stay out of it.
