What does a great empire do when faced with imminent invasion and destruction? It can rearm at home and seek allies abroad; but more cunningly it can revisit its history to forge a myth that will unite the people and carry them through to victory, a myth that will demonstrate to everyone that their country has been specially chosen by history to uphold justice and righteousness. It is what the French did in 1914 and the British in 1940. In such circumstances, history reimagined can be a very powerful weapon.
