To sign up for this Jihad seems either incredibly brave or incredibly stupid, and I'm inclined to the latter view.
That being the case, I wonder whether our ire and accusations of treachery shouldn't be directed at those who incite them to go off to become martyrs, and who organise their journeys.
And while we're at it, perhaps also question what it is that has so alienated some of our fellow citizens to even consider such a drastic form of action, and how our Moslem population might be better 'kept on board'?
