The State of the European Union (SOTEU) is the most important EU annual event. A key moment where the President of the European Commission addresses and debates with the members of the European Parliament. We sat down with Desmond Dinan, Professor of Public Policy, Jean Monnet Chair and EU expert at the Schar School of Policy and Government of George Mason University.  He helps us understand what SOTEU is really all about, why it is important and what to take from this year's edition which took place on September 16.
