People are making many assumptions about this woman when we really don't know much other than the fact that through her own words she is not repentant and doesn't regret anything she's done. The assumption that she is a victim is simplistic and doesn't help address the threat to British safety that thousands of British ISIS supporters returning to the UK poses.
The George Washington University Program on Extremism (in Washington DC) has been tracking foreign fighters who joined ISIS and Seamus Hughes, deputy director of the George Washington program, said there were “thousands of legitimate reasons to question the sincerity” of appeals from people now wanting to return home.
“The foreign women of the Islamic State, while often reduced to simplistic narratives about ‘jihadi brides,’ ‘brainwashing’ and ‘online grooming,’ aided and abetted many of these atrocities and in some cases directly perpetrated them,” he said.
This woman may not have directly participated in bloodshed but she willingly and still without regret helped participate in the Caliphate and contributed to its existence. Don't forget that By the time she joined the caliphate in 2015, its crimes were well documented, including beheading journalists, enslaving and systematically raping women from the Yazidi minority and burning prisoners alive.
I think she'll end up winning an appeal to retain her British citizenship and will return but I don't believe she will ever change her views.
