Not only did his nationality have nothing to do with his success, his father had nothing to do with it. His father was not in his life, and until a few years ago, he was a hardly-successful manager at a small, grungy casino outside of Reno that caters to truck drivers called Boomtown. To say he was not well-liked among the staff would be an understatement (I've been there, and have asked dealers about him...the term "asshole" came up more than once).

It is entirely possible that some Syrians will create the next Apple, and that others will create the next horrific terrorist attack. People are people, and they're all different. The only thing that matters when it comes to immigration is math. Syria and surrounding areas have produced more terrorists per capita than other places. That's a reason to be careful with them, whether or not that is politically correct.
