Too true, mate. US residents know nothing about the role of Canada, Australia, New Zealand, Mauritius, and other Commonwealth members. They think the war was won by Patton and MacArthur singlehandedly. I don't think many people anywhere know a lot about the experiences of Commonwealth troops. I'd suggest "Our War: How the British Commonwealth Fought the Second World War" by Christopher Somerville. It's absolutely brilliant because it allows the participants themselves to recall the war. Includes contributions from really obscure countries.
