When Joe Biden assumes office as U.S. president in late January, one of the thorniest foreign-policy challenges he will inherit is not one of his predecessor’s creation. Indeed, the problem of U.S. relations with Turkey has wrong-footed U.S. administrations from both parties in the past two decades.
