Assad has harbored many Sunni terrorist organizations including al-qaeda. He is only getting what he deserves.
Assad has never harbored al Qaeda terrorists. Besides, how much support can an apostate ruler really afford to offer al Qaeda, whose ideology is to kill infidels in the most gruesome ways? 40 years of Alawite rule and what you allege to be support for al Qaeda has yielded 0 terrorist attacks on American soil whereas less than 10 years of Sunni Islamist rule in Afghanistan yielded 1 attack on 9/11 that killed 3000 American, and dozens of attacks and plots since then.
