Europe is mature enough to mourn these acts of barbarism without descending into civil war or embarking on pogroms.
The days ahead will be hard for some, but our leaders — who gathered a week ago to remember the 13 million who died in WWI, 60 million who died in WWII and the hundreds of thousands killed since — know that the responsibility for what happens next is theirs. These difficult moments will pass.
Spare us the commentary, the fear-mongering, the conspiracy-theories, the appropriation of victimhood, the excuses, the blame, the calls to action, the false patriotism, the ethnocenticism, the propaganda, the pseudo-religious apologetics, the sectarian polemics, the moral equivalence, the misguided lamentations.
Let those who must grieve.
