Oh dear. I think we can already see how this one is going to play out: mud, futility of war, lions led by donkeys, a bit of poetry, a nod to the nurses and the munitions girls and a solemn conclusion that it must ‘never be allowed to happen again’. As we approach the centenary of the Great War, we must strenuously avoid acknowledging that it actually achieved anything, let alone that we were vaguely on the side of right. For that would commit two sins. First, it might upset the Germans. Second, it might suggest that there was actually a point to all that slaughter. And that would never do.
