These will have ties to America, though (anchor babies and such). And that gives them an in.
There might be a tiny ray of hope, now that I've thought about it.
A 12-year-old girl from here in town was in Lebanon for the first time with her father, who is Lebanese. Her mother is American and the girl is native-born in America, too. The parents are divorced. I was never clear as to whether the father in a naturalized American or not - they just said Lebanese. The daughter was traveling with him.
They got out through Syria the first day. The mom had been frantic, so got on TV to cry about it. (She was nice, I didn't mean for it to sound that way - the media sought her out.)
They eventually got to Rome, then Paris, then home to Houston. Cameras were at the passenger lounge to welcome them home, right at the door of the jetway.
The young girl came out, her mom hugged her, her little friends hugged her, she got flowers - so on. I'm sure she had been scared to death and was still in shock, as she never smiled and she kept her head down. Her mom had to push the baseball cap up on her forehead so you could see her face. She did seem more animated when her friends welcomed her.
The camera kept waiting and waiting, focusing on the door - no Dad ever came out. She talked a bit about her dad bribing their way out of the country and through Syria. How lucky they were that he spoke Arabic. Still no Dad coming off the plane.
Eventually, they cut away and the news anchor said the dad had been detained at Immigration. I don't know why, they never said or followed up with it. Can you imagine if there was something in their custody agreement or something like that - like not going overseas or only staying a certain amount of time, whatever - and then war breaks out?
I did see the dad later; he's a firefighter here and seemed OK. Now, that was just one single evacuation, not a whole glob of a crowd - but maybe someone really is checking each and every one out as they arrive. We can hope!
