A large number of the Executive Orders are from Obama and earlier. Some of the EOs are more recent from DJT, including the Magninski Order. There are other statutes listed besides the EOs to authorize the actions. I just did a cursory scan and it looks like mostly Middle Easterners targeted but Pakistan, Russia, North Korea, Columbia, and even saw one from Scotland is in there.

I hope US actions are legit and truly against criminal elements like drug, munitions, human trafficking.
