My first reflection is that Brexit is a war message to the EU. It means NO for cooperation, NO for negotiations, NO for understanding and accepting the political wishes of the EU for peace and solidarity, it means NO for European values, namely it is a big NO for solidarity and a big “NO money” for those who are in the biggest need.
Brexit is a war message to England, too. It means YES for xenophobia and racism, YES for chaos and anarchism, YES for old-fashioned one-nation myth, YES for deepening the split in society, YES for fear and blaming others, YES for not taking responsibility, YES for risking the future, YES for fighting for power, YES for jumping into uncertainty just to show “who has the control”.
What should be done and by whom? The EU should make efforts to come out of this situation in the most positive way. Which means to tighten relations within the EU, and keep within the EU as large parts of GB as possible, first of all those who voted for remaining.
