A US shift marked Kurdish-led forces' fall from power in Syria

The Kurdish-led Syrian Democratic Forces have fallen from power in Syria as the U.S. shifts its backing to the country's new leaders in Damascus. Analysts say the SDF miscalculated, taking a hard stance in negotiations with the new leaders on the assumption that if a military conflict erupted between them, Washington would support the SDF as it had for years when they battled the Islamic State group. Instead, the Kurdish-led force lost most of its territory in northeast Syria to a government offensive after intense clashes erupted in the northern city of Aleppo on Jan. 6.
