There are certain questions that people should not even be asking. Reading is one of man's most noble activities. We read to learn. We read to have a first hand experience of what other people think, about how things were, are or will be. If I want to know about the theory of Marxism, I read Das Kapital and any other works related to Marxism. In the same manner, if I want to know what Hitler wrote or what Hitler thought or what Hitler planned to do, I read Mein Kampf.
I reckon that if people had bothered to read Mein Kampf before the developments that are now history they would have had second thoughts about signing the München Pakt for the partition of Czechoslovakia.
If Western Powers had spent some time analysing National Socialist Ideology, they would have been less prone to think that World War One was going to be the war to end all wars and they would have been much more willing to prepare for what was coming.
Things happen when people are less prepared to cope with a chain of events and the speed of change is such that it becomes some kind of political blitzkrieg. World War Two did not happen overnight but it was a chain reaction, like pieces of a puzzle that fell into place to create one of the biggest tragedies in Human History.
When the mass media are constantly talking about a widespread rise of the so called Far Right and they link what they call Far Right to what started in Continental Europe in the first half of the Twentieth Century, inadvertently they generate huge demand. Thanks to the mass media, more and more people want to read Mein Kampf.
