The European Union has, in practice, lacked genuine free movement of people across internal borders for some time (I went through complete and very aggressive border control entering France via airplane three years ago). Schengen arrangements have been curtailed in Germany[^1]. Part of the challenge is that Europeans appear out of touch with rapidly changing realities (I say this as a European). Additionally, some argue that the European Parliament is operating under an unofficial coup[^2].
The rearmament initiative is particularly concerning. Over the past three years, communities in Italy, Spain, Greece, and Germany have been devastated by flooding, wildfires, etc. Rather than prioritizing investment in resilient infrastructure, leaders are channeling resources into rearmament to confront Russia and China (or so they say - since they are acting as clowns anyway no one really pays attention). My concern is that these weapons may ultimately be used by Europeans against one another; It happened twice already.
