The first sentence of the link you provided states:
“During the Syrian War, the US and other Western countries trained, equipped and paid Syrian rebels to fight the government and, later, root out the Islamic State of Iraq and the Levant (ISIL).”
I’m trying to understand how they trained Syrian rebels to fight Assad’s government AND root out ISIS ( or ISIL if you prefer), and STILL fund ISIS ( the group that supposedly claimed responsibility for the latest Moscow terror attack ). Why root them out and then fund them? 🤔
