This is brexit post truth bollox. #1 The Eu was formed as a response to the endemic conflicts which have plagued the continent for centuries. The development of nation states in the C18-19th did not lead to peace and stability, but two world wars and their revolutionary aftermath that left tens of million dead and a similar number of refugees. Pooling sovereignty and the four freedoms of good services capital and people were there to diffuse the tensions that were at the heart of many of the conflicts. People don't live tidily in borders and xenophobia is a common human frailty. Many current day problems require the resources of more than one country, or require a common response. e.g. balance of power between global companies and governments; scientific collaboration, ecology; refugees; security etc. Membership of a free trade area has benefited Britons, but it isn't what the EU is about #2 EU citizens have as much say in who leads the EU as the British public do about their prime minister. In bioth cases the leader is appointed by democratically elected representatives. #3 Brexit was less of a cry for independence than a long standing British tradition of blaming foreigners when times are tough.
