The European Union needs closer cooperation on markets and defense but not on political issues such as migration, where major differences between countries make this impossible, Hungary’s nationalist Prime Minister Viktor Orban said on September 6. "There are issues, even existential issues, to which we don't have common answers, this is war and peace, migration, gender, labor-based society, full employment," Orban told a conference in Cernobbio, Italy. "If you force us to come together on issues we don't agree, you disintegrate the European Union," he said.
