She wasn’t living under the delusion that she could come back and live with her child in Britain. At that time she already knew that her citizenship had been revoked. The reason that she wasn’t fazed by heads in bins is because they were nothing, they didn’t matter, they were infidels...you know, infidels..like the people in the UK.
Why you’re quoting social services I don’t know, they work in the UK not Syria. There are countless children out there that are presumably British by birth but once they and their parents are out of the country they are not our responsibility. Yes, they are essentially British citizens but it’s not our responsibility to ensure that they are doing the right thing by their families, nor is it our responsibility to interfere in their lives. She chose to live in another country, she’s not had an unfortunate time on holiday.
