American efforts to create a viable armed opposition ultimately failed, with many of the weapons and equipment eventually falling into the hands of radical jihadist groups aligned with al-Qaeda and, later, ISIS. The emergence of ISIS as a regional threat in 2014 led to the U.S. building ties with Syrian Kurds as an alternative vector for implementation of its Syrian policy objectives.
While the fight against ISIS was real, it was done in the context of the American occupation of fully one third of Syria's territory, including oil fields and agricultural resources. As recently as January 2019, the U.S. was justifying the continued presence of forces in Syria as a means of containing the Iranian presence there; the relationship with the SDF and Syrian Kurds was little more than a front to facilitate this policy.
Turkish incursion into Syria is the direct manifestation of the four A's that define the failure of American policy in Syria, Afghanistan, Astana, Adana and Ankara. It represents the victory of Russian diplomacy over American force of arms. This is a hard pill for most Americans to swallow, which is why many are busy crafting a revisionist history that both glorifies and justifies failed American policy by wrapping it in the flag of our erstwhile Kurdish allies.
But the American misadventure in Syria was never going to end well bad policy never does. For the American troops caught up in the collapse of the decades-long effort of the United States to overthrow the Assad government, the retreat from Syria was every bit as ignominious as the retreats of all defeated military forces before them. But at least our forces left Syria alive, and not inside body bagswhich was an all too real alternative had they remained in place to face the overwhelming forces of geopolitical reality in transition.
