I believe the US will move to supporting a 'transition period' where Assad stays in power until a a new democratic government can be set up. So they are still supporting the removal of Assad, but not the immediate removal.
Meaning total support for Assad least he be deposed by force of arms before then? In reality of course, the US is basically out of the game now, with next to no influence as to what happens. We let the genie out of the bottle and then split. So we bomb some ISIS targets, including some in Syria, that accomplishes nothing other than ineffectually attempt to create the chimera that the US is actually doing something worthwhile in this cluster f**k.
