Connecting the dots with the latest military developments:
It appears that the US-led strategy is successfully using airstrikes to corral IS forces away from the Turkish-Syrian border and turn its attention to consolidating eastern Syria by attacking government forces there instead. This will firm up the effective isolation of the Syrian government along the country's western edge and make it more difficult for them to be helped by or link up with friendly Iraqi or Iranian forces.
In the meantime non-IS rebels will be regrouped along the Turkish border to establish dominance in northwestern Syria against both IS and government forces with the help of Turkey and US-led airstrikes. Rebels supported by Jordan will probably push north when the Turkey supported rebels push south in a pincer movement to deliver the killing blow to the Syrian government with IS forces, and probably US-led airstrikes with or without a no-fly zone anywhere, as a wall to the east.
IS will then be sandwiched in between a Western-friendly (or at least Turkey sponsored) new official Syrian government and hostile Iraqi and Iranian forces. The corralling of IS can further be used as an attrition proxy against Iraqi and Iranian forces with continued sponsorship by the Gulf states at minimal cost to the US while the new Syrian government can be groomed and strengthened. If this is indeed the plan being pursued it is a Great Game move par excellence by the Obama administration to restore a regional balance of power at minimal cost to the US and with maximum potential for either extrication or exploitation in the future.
