Dystopian novel "American War" seems more plausible now given tribalism (Vox interview)

Sean Illing of Vox interviews the Canadian-Egyptian author Omar El Akkad, of “American War”, set in 2075.

  

This sounds like a more gradual dystopian future.  Some southern states have seceded and some of the American southwest has been retroceded to Mexico. Coastal cities have been buried by sea level rise, and a third of the country has been killed by bioterror (maybe North Korea). Drones target citizens.

  

The novel describes how a girl Sarat falls into tribal extremism.
