ISIS and the other jihadists need to be defeated by other muslims and not by western intervention, otherwise they will never truly go away.
In Iraq the Sadrist movement seems to be the best hope with a non-sectarian, technocratic government, which will take on the struggle with reduced outside intervention (West,Iran etc)
In Syria, I would like to see a general ceasefire with the rebels while the SAA pushes from Palmyra to Deyr Erzor, then liberates it and expands its control there. Assad must resign with under-the-table guarantees that he will never be prosecuted for war crimes, go to Russia forever and some trusted general should take over so the talks for a transitional government can continue with a victorious but more amiable syrian government.
Yeah, right ...
