Let me start by saying that I can imagine little worse than saying good bye to my parents or children or friends off an on innocent beach holiday and then being confronted not just with their cruel and apparently arbitrary death, but with my grief, and their suffering, being in the full glare of publicity.
There is nonetheless an uncomfortable, semi-symmetry between those travelling north across the Mediterranean to their deaths, and those travelling south. On the one hand, those escaping oppressive regimes across Africa and the Middle East drown in their thousands in leaking vessels run by human sharks, as they flee terror. On the other hand, northern Europeans seeking sun and a holiday break get gunned down by the very terror that is sending people to their deaths in the opposite direction.
It's hard to know which is worse. But I am sure that historians in two hundred years time will look on the geopolitics of the 21st century as in many ways incomprehensibly mad.
