To what extent are European values shared by all Europeans? The question is raised at the national level of each society, but recently, it has also and especially emerged quite forcefully at European Union level. Do its Member States all recognise themselves in this and do they respect it? The most recent political developments, including the cleavage over the migratory policy, highlight a true divorce between East and West in terms of these fundamental values. The question is not just of a theoretical nature, since the European Commission has initiated the triggering of the measure included in article 7 of the TEU against Poland.
