That would be “I-S-I-L” in Obamaspeak, or Isis to everyone else.
and, not Islamic according to Obama
I prefer ISIL because it drops connection to Iraq and Syria. In my mind ISIL is more correct because the term illustrates the fact that the region in question is already severed from Iraq and Syria.
The large view is that Iraq and Syria are no more. They have been sundered into at least two other states being the Kurdish autonomous state and ISIL.
The current efforts are about establishing and stabilizing the precise boundaries of the old and new states.
There is also the question of if the former Syrian Kurdish area will unite with the former Iraqi Kurdish area.
