The terrorist attack in Brussels has scuttled the last glimpse of hope that people of Europe could live without the fear of a sudden death at the hands of dangerous zealots from Islamic State, and that the blood flowing in the Middle East won’t spill over into EU nations.

Or was it even possible to prevent it? And even if not - what should be done to fight the unseen enemy? We ask a former Minister-President of the Brussels region. Belgian politician Francois-Xavier de Donnea is our special guest today.
