According to Professor Ferguson, we need to rethink our understanding of the 20th century. There were not, he says, two world wars and a ‘cold’ war, but a single Hundred Years' War. It was not nationalism that powered these conflicts, but empires. The driving force was not class or socialism – race was. And finally, it was not the West that triumphed; in fact, power slowly and steadily migrated towards the new empires of the East.
