As well, when you don’t trust a foreign government to ensure that people only get passports for their own identity, you can’t be sure that a random person coming in with a passport from said country isn’t actually a Person of Interest.

I also doubt Syria would be much further up the list had the US never set foot there.
Not supporting the US position, but those areas had passport and visa issues well before any US involvement.
