The spread of “Catalan Chain Reaction” to Belgium could give inspiration to Flanders to break off from Belgium. Belgium is a somewhat artificially created state and its dissolution would be the clearest sign yet that the EU’s ruling elite intend to take the bloc down the direction of manufactured fragmentation.

The European Union is an economic and political union between 28 European countries, it's based on the rule of law and governed by the principle of representative democracy, with citizens directly represented at Union level in the European Parliament and Member States represented in the European Council and the Council of the EU. https://europa.eu/european-union/about-eu/eu-in-brief_en
