I'm torn on it.
Initially I felt that revoking her citizenship was the right decision. Yes she was a child, but what she did, to join a terrorist group, was so extreme that I felt nothing but disgust towards her. It's completely beyond my comprehension why anyone would turn their back on a safe country to join ISIS.
However I have since listened to the BBC podcast and watched the documentary and it seems that not only were opportunities to stop her from leaving missed, for example a letter that never actually reached her parents, but she was actually smuggled through by some sort of spy working for Canadian authorities. Surely the authorities must take some of the responsibility for this.
She comes across very badly, weird, detached, unremorseful, entitled. However, she is in a probably dangerous camp with other extremists, she's also lived through horrors for several years now, so who knows what she really thinks or feels.
What is going to happen to her? She can't stay in that camp indefinitely, why should Syria have to have her anyway? Why should Bangladesh or anywhere? There is an argument that it's more dangerous leaving all these people in the camps, there are being radicalised even more and so are the children, the camps aren't secure. What is going to happen to the children.
She wouldn't face trial is she did come back here so she'd end up having to be kept and protected. She's just one, stupid, person so even if you have sympathy for her on some level, why take any risks bringing her back when you consider all the the innocent people who've lost their lives because of terrorism.
But it certainly isn't a straightforward situation and eventually something will have to be done with all the people in the camps.
