Many in Afghanistan that the UK offered asylum to did not make it out, and are now trapped there.

Under those circumstances of chaos and hurry, almost anyone will make mistakes. Perhaps we should not blame the UK and the US for slipping up.

However, the UK government seems in recent years to have become systematically incompetent for all tasks that involve doing things for specific people. Especially those that involve passports and visas.

I don't know whether this is a matter of hiring corrupt or incompetent people, or a workplace culture that makes it better to do nothing than to help anyone who wasn't supposed to be helped, or something else.
