I think people need to take responsibility for their own actions at times.
As mentioned the UK govt advised against all but essential travel a lifetime ago (I know it's really only days but seems like a lifetime ago). At that time they stayed that if people still chose to travel they would basically be on their own to get back.
I would have thought that would have set alarm bells ringing. Plus well everything else that's been going on.
They should bring Nazanin home though if she is freed.
