I struggle in trying to bring the scale of the tragedy home to people in Ireland. Perhaps the best way to make sense of it is to go back to a device we used in our advertising campaign leading up to World AIDS Day last year, in which we asked people to imagine that every week the population of a town in Ireland would be obliterated. Senator Norris mentioned this earlier. Another analogy is our own experience of famine and the degree to which it has seared our history and put its mark on much that has happened since. Imagine the impact in centuries to come of a tragedy on this scale and our failure to stop it.
