Syrians awakened on Monday to a hopeful if uncertain future, after rebels seized the capital Damascus and President Bashar al-Assad fled to Russia, ending a 13-year civil war and more than 50 years of his family’s brutal rule. The lightning advance of a militia alliance spearheaded by Hayat al-Tahrir al-Sham (HTS), a former al-Qaeda affiliate, marked one of the biggest turning points for the Middle East in generations. Assad’s fall wiped out a bastion from which Iran and Russia exercised influence across the Arab world.
