I have a feeling that there are a lot of issues surrounding this rescue that the State Dept is dealing with of which we have no idea. IIRC, many of the people demanding rescue, though Americans, are not supportive of America. I think the US needs to take a lot of care with this--not to mention the logistics of it. OTOH, if I was there like RY2, I wouldn't care much of anything except to get my behind out--in one piece.
Just checking the ID's is probably a nightmare. And now that we're paying the full freight, what do you want to bet that people who aren't American will try and get a free ride to the US just to get out of there and then pay for a flight to their home country later.
