This volume is a collection of thirty papers written by authors from around the world. The writers focus on topics related to their own research interests. As a result, readers obtain a worldwide perspective on World War II from academics working on nearly every continent, proving that World War II was, probably, the first ever truly global experience for humanity. Present are many and different perspectives on the war. Eighty years after the end of World War II, these academics share their knowledge and reflections about a gruesome, but still not very remote time. In the new millennium, their studies should remind readers that the 'end of history' has been an impossible illusion and warn that peace and stability in international relations are not a given.
