"Ar Mageddon" is Hebrew for "City (or Cities) of the Sanctuary." The Revelation appears to be primarily talking about the original sanctuary of God, the Garden of Eden, but it may be that Jerusalem, the home of the second sanctuary, will also be dragged into the war at some point. The dried up Euphrates lies at the epicenter. That is, a vector (or way) drawn from Jerusalem to the epicenter of where Hussein dried up the Euphrates and then extended eastward, points to (and bisects) Baghdad, Raqqa, and Kabul, the home of the three "demon-posssed" kings of the east who start (have started) the final battle between good and evil. Two have already been killed off, the ISIS leader(s) is next in line. For more on Ar Mageddon, see the7lastplagues.com
