About the UK's EU withdrawal
Since the establishment of the nation-state system following the 17th century Treaty of Westphalia, each nation-state has operated with a dual perspective: prioritizing their own national interests (the "real" stance) and prioritizing the survival of Europe as a whole (the "official" stance). This has led to a constant search for a middle ground in the management of national affairs. In the UK's EU referendum, statistics have shown that the Wealthy Class and Highly Educated Layer favored "Remain", while the Working Class and Low-educated layer favored "Leave". If the referendum had been framed as a contrast between the idealism of European coexistence and the realism of "as long as it benefits me", the outcome might have been different. However, the Remain camp's focus on the economic benefits of staying in the EU can be seen as succumbing to the political "illusion" of wanting to be a sovereign state unrestricted by the EU. This can be seen as a failure on the part of Cameron, who initiated the referendum. In times of transition, what is required of rulers is a clear vision, not just short-term financial matters. This is a lesson that the Japanese people can also learn from as an example. However, the conflict between the "European Community" and the nation-state is not a new issue, and this referendum does not mark the end of it.
