International relations is always constant struggle to breath my friend. The most important thing in Syria is (right now) disarmement of PKK/YPG, either through diplomacy or force of arms. I dont trust PKK no matter what, but If it is achieved with diplomacy, it is much preffered and welcomed obviously.I think this is a trap, so sdf gets dismantled but they will incorporate in the central gov and when israel needs it they will start to revolt and sabotage. In the meantime they will give birth to 10 kids and get half of the countries population to be kurd
Once this achieved, the situation will be monitored "constantly", as it should be. If or when Israel needs, sabotages or so on comes after that, then we will act accordingly
Btw, believe me birth rate of Arabs is no less than Kurds. I wouldnt worry about that
