She tried to become a dual nationality, we just didn't recognize it
No. Her other 'official' nationality was originally claimed (by the UK gov) to be Bangladeshi, not "Dae'eshi"(?). But the Bangladesh gov counterclaims that she has
never held that nationality, leaving her with only her British nationality — which Javid is now trying to remove (if he hasn't done it already...?) without the inconvenience of due process.
Yes, she burned her UK (child's) passport, but this was a symbolic gesture of her pledging allegiance to ISIS ('coincidentally' also ensuring that recruits were trapped, even if they later might have had second thoughts — though not in this particular case). That act had no bearing on her actual legal nationality, since — regardless of what they called themselves, or claimed — the ISIS/ISIL leadership was
never in a position to offer 'citizenship' to
anyone. That said though, any UK passport
holder who destroys their UK-issued passport has in doing so quite possibly committed a criminal offence (property damage), since
all UK passports are (AFAIK) legal documents which technically remain Crown property.
So that's possibly something else she could be charged with, along with "being a member of a proscribed/ illegal/ terrorist organisation" — a law which the UK has had on the books for decades, as a means of dealing with e.g. IRA-members or -affiliates who didn't actually carry out any violent attacks
themselves, but 'only' aided and abetted those who did ('aiding and abetting'
also being prosecutable under UK law...)
I certainly don't believe that. I would rather see her rescued from the Syrian justice system.
And as far as I understand things, so would AQ: she has maintained from the start of this thread that Begum should be tried in the UK, not Syria (or Bangladesh!).
Since making her stateless
is actually illegal in the UK,
according to the very law that Javid has tried to invoke, the woman is still at least
de facto British (if not technically
de jure at this point) and is therefore 'our' responsibility — however much we might wish to fob that off onto someone else.
Still, trying to fob off their collective responsibilities whenever possible (and also often when not) is something that Theresa May's government has been doing for
years now (see the CFC Brexit-threads — now in their fifth exciting edition...)
