In fairness, Turkey, Saudi Arabia, and Egypt have long-standing business relationships with the United States, and none have significant outflow of refugees. Dunno about Azerbaijan and uh… Georgia. It's not a surprise that they're not banned.

Libya, Iraq, Iran, and Oman on the other hand have historically not been on good terms with the US and have a lot of tumultuous, often jihadist-related unrest.

15 of the 19 hijackers from 9/11 were Saudi Arabia citizens, 2 from United Arab Emirates, and one each from Egypt and Lebanon , and Donnie himself blamed 9/11 on the arabians, not the iraqis .

Yes, clearly this thing is about fighting terrorism /s.
