Sopron is an example of what we Europeans can achieve if we bravely defend our indivisible values. We must be aware that the national good always depends on the common European good. There is a message for today in the words spoken by German Chancellor Angela Merkel in the evangelical church of Sopron, Hungary, where she recalled, with the Hungarian Prime Minister Viktor Orbán, the 30th anniversary of the pan-European picnic. On 19 August 1989, Hungary opened the borders with Austria for three hours, in theory for a picnic in the name of international friendship. In practice allowing 700 tourists from East Germany to move to the West. A global event, as Merkel called it yesterday: the first blow to the wall that divided the citizens of the DDR from the West and that three months later would have completely collapsed.
