Churchill, Hitler and the Unnecessary War: How Britain Lost Its Empire and the West Lost the World, is a book by Patrick J. Buchanan, published in May 2008. Buchanan argues that both world wars were unnecessary and that the British Empire's decision to fight in them was disastrous for the world. One of Buchanan's express purposes is to undermine what he describes as a "Churchill cult" in America's élite and so he focuses particularly on how Winston Churchill helped Britain get into wars with Germany in 1914 and again in 1939.
