My parents and wife were born in Syria. I lived and studied there for 5 years, and spent some time in then-liberated Eastern Aleppo in 2013.
I, and most Syrians I know, despise Obama not because he said Assad should step down; we despise him for not following through, or at least getting out of the way and letting regional players help Syrians get rid of Assad, and kick out Iran's sectarian militias.
Western powers are responsible for a lot of horror and misery around the world. But unlike Iraq in 2003, Libya and Syria in 2011 experienced genuine popular uprisings. Most of the death and destruction was caused not by the West, but by Gaddafi and Assad.
Despite what Noam Chomsky seems to believe, the West is not the source of all evil in the world.
