Twenty five years ago, in the aftermath of a devastating famine in Ethiopia, remembered for better and worse for Bob Geldof's Bandaid concerts, I wrote a book called "Famine: A Man-Made Disaster?" The question mark said it all. I ghostwrote the book for a group of African and other leaders who were more tentative than I was in declaring what had happened was largely the fault of African governments. So the great men added a question mark.
