May be. But I really believe that there is a tacit understanding between the ISIS and the Israelis. The reasons are:
1. ISIS hasn't attacked the Israelis till now.
2. Israelis have bombed the Syrian Army positions, in areas where they were fighting the ISIS. This indirectly helped the Islamic State to conquer these locations.
3. Israelis have shot down a number of Syrian Air Force fighter jets, inside the Syrian borders. All of these jets were shot down in regions where the Syrian Armed Forces are engaged in active combat with the ISIS.
