"Last month, it was revealed that U.S. President Donald Trump had quietly ended his government’s four-year-old program to train and arm Syrian rebels fighting Bashar al-Assad’s regime."

Syria is a mess because of the West's actions - just like Iraq is a mess because of the West's actions. The West was never in Syria for Syria, but to oppose Syria. Desisting creating and supporting terrorists in Syria is the first thing that the West has done for Syria since before the conflict began.
