Ben Fountain’s satirical first novel, 2012’s “Billy Lynn’s Long Halftime Walk,” has raced to the silver screen, directed by Ang Lee no less.

In the month since an Iraqi forces-led operation began to liberate Mosul from so-called Islamic State (ISIL), more than 47,000 people have been displaced.

As the fight for Mosul rages on, leaders outside Iraq are discussing the possible, potentially damaging, consequences of retaking the city from ISIL.
