"The ruling elites in Britain and France failed to realize in time that they were not dealing with a slightly more excitable version of Weimar’s Gustav Stresemann or Heinrich Brüning. Hitler was a new phenomenon: an ideologically driven leader who sought not reasonable national satisfaction but absolute power. How did so many people miss seeing this catastrophe in the making until it was (almost) too late? Professional property and industrial developers use (when they can get away with it) a clever but none-too-moral method of gaining permission from the planning authorities for dubious projects. This entails applying for – and being granted – a succession of minor, apparently reasonable, and not necessarily dangerous-looking permissions until, in effect, these accumulate into a permitted project that would not have been allowed had the authorities been presented with the overall plan from the start. This is known in the business as ‘salami slicing’. With hindsight, we can see that Hitler was adept at the ‘salami-slicing’ technique in his relations with the British, French, Czechoslovaks, Poles and other interested parties during the later 1930s. By 1939, showing his characteristic mixture of boldness and guile, the Führer had accumulated what he needed, in territory, diplomatic clout and military strength, in order to dominate Europe – not to mention, potentially, the Eurasian lands to the east. During this same year, the democratic powers began to realize the true extent of his aims. Of course, by then it was far too late to thwart him without resorting to massive force."
