I like any story that reminds me of my own undoubted ignorance. Had you previously heard of Fazul Abdullah Mohammed? I hadn't. I am genuinely ashamed to have forgotten - totally forgotten - last year's World Cup bombings in Uganda. Nor did I know much, if anything, about the UN Al Qaida and Taliban Sanctions Committee and its British head, Richard Barrett. As to what we do in Syria, I don't know. It is easy to identify problems, harder to identify solutions.
