"You started it. You invaded Poland" shouted Basil Fawlty, as the hapless Torquay hotelier's attempt to not mention the war to his German guests unravelled into goose-stepping embarassment. The Fawlty Towers' satire on the British cultural obsession with Hitler and the Nazis still strikes a chord, 30 years on. The cultural power of the Second World War could even threaten to overshadow next year's First World War centenary.
"You started it. You invaded Belgium" is what Basil might have shouted at his guests if he had been desperately trying not to mention not that war, but the one which came first. Yet that joke would have been lost on most people. For Poland is still the most popular choice when people are asked to identify the cause of Britain's 1914 declaration of war on Germany, which came almost exactly 99 years ago. Just 13 per cent recall enough of the story of "plucky little Belgium" to get the answer right.
