Actually it was a question?
I did not look at the EO at all. It doesn't affect certain countries?
Actually looking at the EO might be a good place for you to start. According to those who have (quoted up thread), it does not mention specific countries but rather increases the restrictions placed by the Obama administration on countries likely to produce terror threats which is where the list came from. Next you might say that the Obama administration was careful to only include countries that Trump hasn't done business with, who knows?
In any event though, while you may be able to come up with other countries that pose an existing terror threat from large segment of their citizenry, you do have to admit that the countries on this list kind of make up an all-star team in that category, no?
