The policy in this area has been messy and deadly in recent years.
The Syrian Civil War with Qatar, Saudi Arabia, Hillary Clinton, John McCain, the Neocons, Israel and the Israel Lobby aligned against Assad some more openly than others has disastrous consequences.
The war itself brought misery to Syria and the Al-Qaeda (Bin Laden sympathizers) funded by the Saudis and Qataris morphed into Islamic State.
IS atrocities and IS terrorism are in part the responsibility those who opposed Assad from the outside and promoted the war against his regime.
Yes, Obama set the entire ME on fire.
However, Assad is not one of the “good guys”.
And ISIS is truly a Great Evil. (that is about to end)
The core of ISIS was Saddams military. Saddam was Baath Party dictator as is Assad.
