The Institute for the Study of War (ISW) seems to be doing a rather good, detailed job of analyzing and reporting ISIS’ actions and strategies in Syria and Iraq. They have published a report in pdf form which they have made available for downloading.
There is a map of Syria and Iraq showing the areas of ISIS control on the bottom-half of page 3. Interesting that the colored zones are in red and black – the colors of the Second and Third Signposts, respectively. The map reminds me of the words of Daniel 8:4, “I watched the ram as he charged toward the west and the north and the south. No animal could stand against him, and none could rescue from his power.”
So where might the Iranian ram charge to the west and to the north? It might be a good bet Iranian forces will follow the red and black highlighted roads on that map to start with in order to completely finish ISIS. So we might be looking at a map of the Iranian advance as it is to happen in the not-too-distant future.
