Al-Sharaa, Petraeus, and the End of the War on Terror: A Most Revealing Episode at the UN General Assembly

Recently Ahmed al-Sharaa (formerly al-Julani) met with David Petraeus at the UN General Assembly. It was a unique moment that quite a few news outlets found worthy of note. And while some saw it has symbolic, few reflected on its actual meaning.
They tended to focus on how far al-Sharaa had come, how he had once been a prisoner of the US, and a member of al Qaeda. And yet (supposedly) he has renounced his previous Salafism and is now being put forward as a leader that will turn Syria toward Western Liberalism, democracy, and the rule of law - or so they hope.
