ON NOV. 10, THE TRUMP ADMINISTRATION announced that the U.S. would stop refueling Saudi warplanes engaged in the bombing of Yemen, a move hailed by some as a sign that U.S. support for the Saudi project, in its fourth year, is waning. Three days later, the Saudis provisionally agreed to allow evacuation of some wounded from among the rebels they’re fighting, a condition the U.K. said had been a key hurdle at peace talks that collapsed in September.

If this condition has thwarted the peace talks, why the author hints that the progress might be made toward peace? Thank you for your help.
