Americans will debate the American drone strike that killed the Iranian commander Maj. Gen. Qassim Suleimani for a long time: whether it was wise, what it means for the Middle East, and how to proceed.

It appears that in undertaking the strike, the Trump administration may have sacrificed a valuable American counterterrorism partnership with Iraq at the altar of a risky pressure campaign against Iran with no end in sight.
