Sorry, but it's hard for me to have any sympathy and/or concern for any American 'stranded' in Afghanistan today.
They knew seven months ago that this day was coming.
These are probably the same people who show up late everywhere.
And as I said from the start, the U.S. State Department has done them a favor of sort, choosing to let the Taliban know where to find you. At this point, you're more valuable alive than slaughtered...to all parties.
