Some celebrities, at least, are modest enough to know what they don’t know. Here (via the London Evening Standard) is Paul McCartney on the war in Iraq:

“If Japan bombed Pearl Harbour, it’s clear what you have to do – you have to be at war with Japan,” he said. “But this is a very difficult situation. It’s hard to know what anyone should do. I’m just like anyone else – I’m just watching it unfold…I’m not a politician.”
