DEBATE: In recent public comments, German Chancellor Angela Merkel and French President Emmanuel Macron talked about the possibility of a collective European army. This subject had been raised within Europe even prior to the presidency of Donald Trump, who is skeptical about NATO. In 2015, President of the European Commission Jean Claude Juncker discussed his intention to work toward this end. Despite the establishment of so-called permanent structured cooperation (PESCO), obstacles and difficulties remain. BESA joins the debate by posing the question: Is an EU army possible?
