It further reduces the possibility of tourism to these 7 countries, due to the knowledge that if I want to go to the US, I face a much more invasive immigration check (see Norway PM), and the possibility of denied entry, which carries a lasting stigma.
Clearly tourism in Syria is not an option at the moment, but the more adventurous European could certainly want to visit Iran. And of course it was true that immigration officers could have asked about those trips before this order. Nevertheless, I feel that my choices of holiday have been affected by this order.
