Why Deir el-Zour?
I think you need to read the real estate agent's listing to see why ISIS chose this place:
"The perfect starter town to show your parents and friends that you have it together; this town boasts two bathrooms, both in working order.
But never fear -- the town is big enough in case you want to "avoid your guests" by hiding out in there. Architecturally designed nooks AND crannies for chilling out during those awkward moments when you need a break from drones & those insistent smart bombs.
In the event that you do feel like socializing and entertaining, take a walk down to the kitchens complete with granite countertops and "a large pantry which is perfect for storing your gluten-free Bisquick." Score.
Location is everything in real estate, and this town has it locked down. For starters, the seller ensures that "you will have no problem getting your fit bit steps in each day." Dodging & weaving during air and missile attack is the perfect aerobic exercise.
The town has, in walking distance, all of the downtown shops, restaurants and trendy workout joints (where you can "throw on your Lululemon and work it off," of course).
If kids are a part of your family, you're in luck, as getting them to school will become infinitely easier as there aren't any."
I believe ISIS has many hipster members.
