Now all the women and girls of Afghanistan will have to suffer the consequences of what has happened.
The UK has been "into Afghanistan" a number of times in the past and it has never ended well. I fully expect that we will have to "go into Afghanistan" again with our allies at some point in the future. It maybe in 5 years, 50 years, or 150 years time, who knows?
The obvious alternative to what is happening now is for the Western Allies to go back into Afghanistan fully now. If we have to do it at a later date it could prove much more difficult and costly.
