[...] a more analytically fruitful approach is to examine the impact of the First World War. Here, for the first time in modern Europe, we see [...] the willingness of the state to incarcerate huge numbers of civilians considered threatening. This statement was the one I found most intriguing in the entire article, but then the author did not expand on it. Maybe he does so in his book. It was strange to me to consider that this state of the world has not always been the norm. When I looked into it, I found conflicting sources of information. Anyone with knowledge on the subject feel like expanding on this?
