The First World War was the unavoidable recent reference point for leaders planning in 1939, though it was not necessarily the closest strategic analogy. The earlier conflict drew in participants from around the world while keeping its main strategic center in Europe. In the Second World War, campaigns beyond Europe had far greater independent importance, making its geography resemble the Seven Years' War in important ways. Historical experience remains useful when planners test which features of an earlier conflict match the new problem. The closing question asks which wars shaped the First World War generation in turn, reminding viewers that analogies form a chain of inherited assumptions.

The conclusion argues that leaders had little choice but to learn from 1914-18, yet the geography and independent importance of worldwide campaigns made the Seven Years' War a useful additional comparison.
