The assailants came at dusk, creeping on foot through the dusty palm groves near the Tigris River, armed only with a rocket-propelled grenade, a light machine gun and Kalashnikovs. They had laid roadside bombs to kill anyone who rushed to help the unsuspecting local guards, who were in their sights.

When the attack on the village last month was over, nine members of a Sunni tribe that had opposed the Islamic State were dead and four were wounded, one of them nearly burned to death. This is the Islamic State in Iraq in 2020: low-tech, low-cost, rural, but still lethal. And while it has not carried out attacks on the scale that it did a few years ago, the number of attacks has begun to grow again.

As American and Iraqi negotiators begin a new round of strategic talks on Thursday, the question of how to respond to the Islamic State’s quiet resurgence — and how much American help is required to do so — will be at the center of the discussion.
