If Hungary does not protect its borders, the European Union’s single market could collapse, Prime Minister Viktor Orbán told a forum in Berlin on Monday. As Hungary is an open country, border defence should be an integral part of its economic policy, Orbán told the forum focusing on Hungarian-German relations. The prime minister said that in the period to come there would be a pressing need for political security, energy security and physical security. Political security is guaranteed by the government’s stability, physical security by a number of factors, including the country remaining an island of peace, and energy security by Hungary’s gas reserves being sufficient for six months, Orbán said. “Those who cooperate with us will benefit from it,” he said.
