Apparently there are between 5000-10,000 Americans scattered throughout Afghanistan, cut-off from the airport in Kabul and there aren't any plans, according to Biden spox John Kirby, to get them to the airport.
Here is what is unspoken and I will say so now because no one else is: The conditions are set right now for the Kabul airport to be a 2021 replay of the last stand of Gandamak, but with the USMC & 82nd Airborne playing the role of the 44th (East Essex) Regiment of Foot.
It's the Taliban's call.
Meanwhile, it looks as though a number of ISAF Coalition members have taken far too long & shown too much lethargy. It may soon be too late:
