I think that the Turkish recent moves there in Syria are more about laying the groundwork for how to take the largest chunk of Syria when the US is inevitably done and gone in a few years. They are preparing for the future with it. How to take the most influence possible from Iran. That's why there is no immediate payback. But, now that they have broken the strong, Iran-friendly, and more centralized Assad-regime, and laid their own foundations more, I predict they will take the entire northern Syria in the future.
