To even attempt to broach this demanding topic in a few hundred words is to rush in where angels fear to tread.
So first a preliminary word: this will not be exhaustive. It will not be ‘exhausting’ either, for which you may breathe a sigh of relief, because of its appropriate brevity.
But the temptation in such a piece as this, on such a topic as that, is to attempt to provide ‘bullet points’ on all the major aspects that should be addressed (for instance, suffering, providence, war, religion, martyrdom, death, bravery, rescue missions, firefighters, security, to name but a few, and not to mention the massive secondary ‘literature’ about the event ranging from the popular urban legends to the more diatribe-like, probably academic too). Instead, I will simply attempt the topic of ‘hermeneutics’.
