It is too complicated, too many factions. So the US teams up with the Rebels to rid ISIS or is it an undercover operation to have them overtake Chemical Assad today. What are Donald's true intentions, it's not like TheDonald started aiding the Rebles. asaik, TheRebels been asking for support to take out Chemical Assad but the US hasn't responded in kind. Only God knows TheDonald's intentions.
The "real" problem is the WMD gassing innocent people to rid rebels in which would be a hard task to do in that situation. Why didn't Donald bomb all of Syria's air bases if he had the intentions or replacing Chemical Assad? Honestly TheDonald knows from Bush's, Obama's fault dealing with the MidEast. But with Chemical Assad using the WMD, TheDonald may have no choice but to look for a regime change. You should be blaming Chemical Assad not Donald. As far as how the situation played out, it wasn't Donald wanting to take out the airfield but of Donald responding to the use of WMD's.
