Pentagon broadens its campaign against ISIL in Syria with the deployment of US marines.

US marines are being sent to Syria to reinforce the fight against the Islamic State of Iraq and the Levant (ISIL/ISIS) armed group.

Together with heavy artillery, the marines are prepared to back up forces they have trained to fight in Raqqa, ISIL's self-declared capital.

What is the endgame? What happens if and when ISIL is defeated?
