The SDF (composed mostly of KURDS) are fighting ISIS effectively and are thus allied with the U.S.. But it would be wrong to call them, or conflate them with, “Rebels”. In a very real sense, they are allied with Assad in that they do not fight Assad’s forces but instead cooperate & coordinate with the government forces. The “rebels” are Islamists allied with the Islamist Erdogan Turks and these “rebels” fight both Assad AND the Kurds.
