Peter Singer: Do countries have a right to secede?
COMMENT: Peter Singer, Professor of Bioethics at Princeton University and Laureate Professor at the University of Melbourne, looks at the Scottish independence referendum debate within the context of the EU and Spain's long-running opposition to Catalan independence.
The European Union has brought 28 countries into a closer political and economic union. Paradoxically, it has also made it more feasible to contemplate the breakup of some of those countries.
Independence for a small state outside of a political and economic group like the EU would be risky nowadays. Within the EU, however, the barriers between states – and thus the economic and political risks of independence – are lower.
