What happened in Manchester on 22 May is of course a tragedy and an atrocity. However, as I take in the images of the dead children and their grieving relatives, the memorials, the news items, the interviews, the debate and the double-page spreads, I can’t help but think of those countless other children who have been killed in their schools and hospitals and homes by the bombs of the West and its allies in countries like Syria, Iraq, Yemen, Afghanistan and Palestine. They too had hopes and dreams; they too have parents, friends, neighbours and relatives who grieve and feel anger and despair. I did not see their pictures, and I do not know their hopes and dreams, but are their lives worth any less than ours? Is their grief or their anger and despair any less valid than ours? Of course not, and if that is the appearance we give, then we should be ashamed.
